[Document Name] Specification 
[Title of the Invention] ANTI-MPL ANTIBODIES 
[Technical Field] 
[0001] 

The present invention relates to anti-Mpl antibodies. 
[Background of the Invention] 
[0002] 

Thrombopoietin (TPO) is a factor that enhances the differentiation and maturation of 
megakaryocytes (platelet precursor cells) from hemopoietic stem cells into platelets. TPO also 
functions as a cytokine with an important role in the regulation of platelet number. TPO is 
converted into its active form through the cleavage of a TPO precursor comprising 353 amino 
acids. 

[0003] 

Mpl is a TPO receptor, and human Mpl molecules are known to exist in two forms 
comprising 572 and 635 amino acids. The human Mpl gene sequence has already been 
analyzed (see Non-patent Document 1 and GenBank accession No. NM_005373). 

[0004] 

Most cytokine receptors dimerize upon ligand binding, and transduce signals into cells. 
It has been reported that TPO similarly binds to its own specific receptor MPL, which leads to 
dimerization of the receptor, thereby transducing signals into cells and exerting physiological 
effects (see Non-patent Document 2). 

[0005] 

Antibodies exhibiting agonistic activity have been reported among those antibodies that 
bind to receptors having the above features. 

For example, an antibody against the erythropoietin (EPO) receptor has been reported to 
substitute for erythropoietin function. The monovalent form (Fab) of the antibody is capable of 
binding to the EPO receptor but is unable to transduce signals. Thus, dimerization of the 
erythropoietin receptor via bivalent binding is assumed to be essential for signal transduction 
(see Non-patent Document 3). 

[0006] 

Antibodies that bind to Mpl and exhibit TPO agonistic activity have also been reported 
(see Non-patent Documents 4 and 5). This suggests that receptor dimerization is induced upon 
binding of a bivalent antibody with regards to MPL as well. 

[0007] 

Meanwhile, a single-chain antibody (scFv) has been reported to exhibit TPO agonistic 



JP 2004-071763 



activity (see Patent Document 1). However, it has been revealed that, the underlying 
mechanism of scFv exhibiting TPO agonistic activity is that a part of scFv dimerizes (diabody) 
and this diabody becomes the actual active unit (see Patent Documents 2 to 4).

[Disclosure of the Invention] 
1 5 [Problems to be Solved by the Invention] 

[0009] 

The present invention was achieved in view of the above circumstances. An objective 
of the present invention is to provide novel anti-Mpl antibodies having TPO agonistic activity. 
[Means for Solving the Problems] 
20 [0010] 

The present inventors performed exhaustive research to solve the above objective. The 
present inventors prepared and purified anti-human Mpl antibody VB22B, and established a 
single-chain antibody expression system using genetic engineering techniques. Specifically, the 
variable region of anti-human Mpl antibody was first cloned, and a diabody expression vector 

25 pCXND3-VB22B db for the anti-human Mpl antibody was prepared. This pCXND3-VB22B 
db vector was then used to generate an expression vector pCXND3-VB22B sc(Fv) 2 for 
anti-human Mpl antibody sc(Fv) 2 . Anti-human Mpl sc(Fv) 2 was expressed in CHO-DG44 cells 
using the expression vector pCXND3-VB22B sc(Fy) 2 , and then purified from the culture 
supernatant. In control experiments, VB22B diabody was transiently expressed in COS7 cells 

30 using the above pCXND3-VB22B db vector, and then purified from the culture supernatant. 

[0011] 

In addition, VB22B diabody and VB22B sc(Fv) 2 were evaluated for their TPO-like 
agonistic activities. The results showed that VB22B diabody and VB22B sc(Fv) 2 exhibit higher 
agonistic activities compared to VB22B IgG, and thus activities equivalent to or higher than that 
35 of the natural ligand, human TPO. 

[0012] 



11 



JP 2004-071763 



Furthermore, the present inventors succeeded in preparing three types of humanized 
VB22B sc(Fv)2. The TPO-like agonistic activity was also proven to be unaltered by 
humanization. 

[0013] 

More specifically, the present invention relates to: 

(1) an antibody comprising a single-chain polypeptide having binding activity against 
TPO receptor (Mpl), wherein said antibody comprises two heavy chain variable regions and two 
light chain variable regions; 

(2) the antibody of (1), wherein the two heavy chain variable regions and the two light 
chain variable regions are arranged in the order of heavy chain variable region, light chain 
variable region, heavy chain variable region, and light chain variable region from the N terminus

[Effects of the Invention] 
[0014] 

Recombinant human TPOs have been tested as therapeutic agents for 
chemotherapy- induced thrombocytopenia in various clinical trials. In these trials, a major 

15 problem that was reported was the production of anti-TPO antibody in TPO-treated patients 
(Junzhi Li, et al., Blood (2001) 98: 3241-324; Saroj Vandhan-Raj, et al., Ann. Intern. Med. 
(2000) 132: 364-368). Specifically, production of neutralizing antibodies that inhibit 
endogenous TPO activity, and the resulting onset of thrombocytopenia, were reported. 
Administration of agonistic minibodies (low molecular weight antibodies) against anti-TPO 

20 receptor of the present invention does not induce the production of antibodies against 

endogenous TPO. Furthermore, since antibody miniaturization results in increased specific 
activity and short half-life in blood, the effective concentration in blood can be easily regulated, 
presenting a further clinical advantage. Accordingly, the present antibodies are expected to be 
therapeutic agents for thrombocytopenia which are more effective than naturally-occurring TPO 

25 or its agonistic antibodies. Furthermore, since minibodies are not glycosylated, expression 

systems for expressing the recombinant proteins are not limited, and minibodies can be produced 
in any expression system such as cell lines from mammals, yeast, insect cells, and E. coli. 
Since binding specificity against mutant TPO receptor is different from that of TPO, minibodies 
are expected to bind specific mutants and show agonistic activity against mutated TPO receptor 

30 detected in the CAMT patients, who genetically have mutated TPO receptor and develop 
thrombocytopenia. 

[Best Mode for Carrying Out the Invention] 
[0015] 

The present invention provides antibodies that bind to the TPO receptor (Mpl). 
35 [0016] 

The antibodies of the present invention comprise all types of antibodies, including 



18 JP 2004-071763 



antibodies with modified amino acid sequences, such as minibodies, humanized antibodies, and 
chimeric antibodies; antibodies that have been modified by binding with other molecules (for 
example, polymers such as polyethylene glycol); and antibodies whose sugar chains have been 
modified. 
5 [0017] 

Mpl of the present invention may be a mutant receptor. A mutant receptor of the 
present invention is usually a receptor that exists at a frequency lower than 50%, preferably 
lower than 20%, more preferably lower than 10%, and even more preferably lower than 1%. 
The frequency is generally calculated using randomly selected subjects. However, the 

1 0 frequency may vary depending on the country, area, sex, and such. Therefore, the frequency 
may also be calculated, for example, within a defined country or area, such as Japan, the United 
States, and Europe, or calculated for one sex. When there are two or more mutations in a 
receptor, the frequency may be calculated for multiple mutation sites or for any one of the 
mutation sites. Mutant receptors are preferably evaluated by a frequency as described above. 

1 5 However, mutant receptors can also be evaluated, for example, by their signal transducing ability 
and such. Specifically, for example, when two different receptors are present, the one with 
stronger transducing signals upon natural ligand-binding maybe be used as a non-mutant type 
receptor, and the one with weaker transducing signals as a mutant receptor. 
[0018] 

20 In one embodiment, the mutant receptors of the present invention comprise receptors 

that are associated with disease onset. The phrase "mutant receptors associated with disease 
onset" means that the loss of reactivity to a natural ligand becomes part of the reason that 
triggers disease onset. In the present invention, the mutant receptor may be a contributing 
factor, but not necessarily the sole factor triggering disease onset. Many reports have been 

25 previously published that describe the association of mutant receptors with disease onset. In 
addition to those that have been reported, associations of mutant receptors and disease onset can 
also be identified by statistical analysis methods (for example, correlation analyses). 
Correlation analyses, also called "case control studies", are well known to those skilled in the art 
(for example, Nishimura, Y., 1991, "Statistical analysis of polymorphisms", Saishin Igaku, 

30 46:909-923; Oka, A. et aL, Hum. Mol. Genetics (1990) 8: 2165-2170; Ota, M. et al, Am. J. Hum. 
Genet. (1999) 64: 1406-1410; Ozawa, A. etai, Tissue Antigens (1999) 53: 263-268). For 
example, the correlation between a mutant receptor and a disease can be studied by computing 
the frequency of the mutant receptor in patients and healthy subjects, and testing whether the 
patient population has a higher mutant receptor frequency. Typically, differences in frequency 

35 are evaluated using the x-test. % is obtained by the equation % 2 = Z (observed value - expected 
value) /expected value. A p value is obtained from the x value determined. Based on this p 



JP 2004-071763 



value, it can be determined whether there is a correlation between the mutant receptor and the 
disease. For example, when p<0.05, the mutant receptor is considered to correlate with the 
disease. Mutant thrombopoietin (TPO) receptors have already been reported (Matthias 
Ballmaier et aL, BLOOD (2001) 97 (1): 139; and others). 
5 [0019] 

It is preferable that the antibodies of the present invention have agonistic activity against 

Mpl. 

In a preferred embodiment, the antibodies of the present invention comprise, for 
example, minibodies. 

10 The minibodies comprise antibody fragments lacking portions of the whole antibody 

(for example, whole IgG). The minibodies are not particularly limited as long as they have 
binding activity to their antigens. The minibodies of the present invention have markedly 
higher activities compared to their corresponding whole antibodies. There are no particular 
limitations on the antibody fragments of the present invention as long as they are portions of the 

1 5 whole antibody, and preferably contain heavy chain variable regions (VH) and/or light chain 
variable regions (VL). The amino acid sequences of VH or VL may contain substitutions, 
deletions, additions and/or insertions. Furthermore, the antibody fragment may also lack 
portions of VH or/and VL, as long as it has binding ability to its antigen. In addition, the 
variable regions may be chimerized or humanized. Such antibody fragments include, for 

20 example, Fab, Fab', F(ab')2, and Fv. An example of a minibody includes Fab, Fab', F(ab')2, Fv, 
scFv (single-chain Fv), diabody, and sc(Fv)2 (single-chain (Fv) 2 ). 
[0020] 

Herein, an "Fv" fragment is the smallest antibody fragment and contains a complete 
antigen recognition site and a binding site. The "Fv" fragment is a dimer (VH-VL dimer) in 
25 which a single VH and a single VL are strongly linked by a non-covalent bond. The three 

complementarity-determining regions (CDRs) of each of the variable regions interact with each 
other to form an antigen-binding site on the surface of the VH-VL dimer. Six CDRs confer the 
antigen-binding site of an antibody. However, a single variable region (or a half of Fv 
containing only three CDRs specific to an antigen) alone is also capable of recognizing and 
30 binding an antigen although its affinity is lower than the affinity of the entire binding site. 

[0021] 

scFv contains the VH and VL regions of an antibody, and these regions exist on a single 
polypeptide chain. Generally, an Fv polypeptide further contains a polypeptide linker between 
VH and VL, and therefore an scFv can form a structure required for antigen binding. See, 
35 Pluckthun "The Pharmacology of Monoclonal Antibodies" Vol. 113 (Rosenburg and Moore eds. 
(Springer Verlag, New York, pp.269-315, 1994) for the review of scFv. In the present invention, 



20 



JP 2004-071763 



linkers are not especially limited as long as they do not inhibit expression of antibody variable 
regions linked at both ends of the linkers. 
[0022] 

The term "diabody" refers to a bivalent antibody fragment constructed by gene fusion 
5 (Holliger P et al , Proc. Natl. Acad. Sci. USA (1993) 90: 6444-6448; EP 404,097; WO 93/1 1161 
and others). Diabodies are dimers comprising two polypeptide chains, where each polypeptide 
chain comprises a VL and a VH connected with a linker short enough to prevent interaction of 
these two domains, for example, a linker of about five residues. The VL and VH encoded on 
the same polypeptide chain will form a dimer because the linker between them is too short to 
1 0 form a single-chain variable region fragment. As a result, the polypeptide chains form a dimer, 
and thus the diabody has two antigen binding sites. 
[0023] 

sc(Fv) 2 is a single-chain minibody produced by linking two units of VH and two units of 
VL with linkers and such (Hudson et aL, J Immunol. Methods (1999) 231 : 177-1 89). sc(Fv) 2 
1 5 exhibits a particularly high agonistic activity compared to the whole antibody and other 
minibodies. sc(Fv)2 can be produced, for example, by linking two scFv molecules. 

In a preferable antibody, the two VH units and two VL units are arranged in the order of 
VH, VL, VH, and VL ([VH]4inker-[VL]-linker-[VH]-linker-[VL]) beginning from the N 
terminus of a single-chain polypeptide. 
20 [0024] 

The order of the two VH units and two VL units is not limited to the above arrangement, 
and they may be arranged in any order. Examples of the arrangements are listed below. 
|VL]-linker-|yH]-linker-|yH]-linker-|yL] 
|yH]-linker-|yL]-linker-|yL]-linker-|yH] 
25 |yH]-linker-|yH]-linker-[VL]-linker-[VL] 
|yL]-linker-[VL]-linker-[VH]-linker-[VH] 
|yL]-linker-|yH]-linker-|yL]-linker-|yH]

The linkers to be used for linking the variable regions of an antibody comprise arbitrary 
30 peptide linkers that can be introduced by genetic engineering, synthetic linkers, and linkers 
disclosed in, for example, Holliger, P. et aL, Protein Engineering (1996) 9 (3): 299-305. 
Peptide linkers are preferred in the present invention. There are no limitations as to the length 
of the peptide linkers. The length can be selected accordingly by those skilled in the art 
depending on the purpose, and is typically 1-100 amino acids, preferably 3-50 amino acids, more 
35 preferably 5-30 amino acids, and even more preferably 12-18 amino acids (for example, 15 
amino acids).

1 5 (Gly Gly Gly Gly Ser) n 
(Ser Gly Gly Gly Gly) n 

where n is an integer of 1 or larger. The lengths and sequences of peptide linkers can 
be selected accordingly by those skilled in the art depending on the purpose. 

In an embodiment of the present invention, a particularly preferable sc(Fv)2 includes, 
20 for example, the sc(Fv)2 below. 

[0027] 

[VH] -peptide linker (15 amino acids)- [VL] -peptide linker (15 amino 
acids)-[VH]-peptide linker (15 amino acids)-[VL] 
[0028] 

25 Synthetic linkers (chemical crosslinking agents) include crosslinking agents routinely 

used to crosslink peptides, for example, N-hydroxy succinimide (NHS), disuccinimidyl suberate 
(DSS), bis(sulfosuccinimidyl) suberate (BS 3 ), dithiobis(succinimidyl propionate) (DSP), 
dithiobis(sulfosuccinimidyl propionate) (DTSSP), ethylene glycol bis(succinimidyl succinate) 
(EGS), ethylene glycol bis(sulfosuccinimidyl succinate) (sulfo-EGS), disuccinimidyl tartrate 

30 (DST), dismfosuccinimidyl tartrate (sulfo-DST), bis[2-(succinimidoxycarbonyloxy)ethyl] 
sulfone (BSOCOES), and bis[2-(sulfosuccinimidoxycarbonyloxy)ethyl] sulfone 
(sulfo-BSOCOES). These crosslinking agents are commercially available. 
[0029] 

In general, three linkers are required to link four antibody variable regions together. 
35 The linkers to be used may be of the same type or different types. In the present invention, a 
preferable minibody is a diabody, even more preferably, an sc(Fv) 2 . Such a minibody can be 



22 



JP 2004-071763 



prepared by treating an antibody with an enzyme, for example, papain or pepsin, to generate 
antibody fragments, or by constructing DNAs encoding those antibody fragments and 
introducing them into expression vectors, followed by expression in an appropriate host cell (see, 
for example, Co, M. S. etal.J. Immunol. (1994) 152: 2968-2976; Better, M and Horwitz, A. H., 
5 Methods Enzymol. (1989) 178: 476-496; Pluckthun, A. and Skerra, A., Methods Enzymol. 

(1989) 178: 497-515; Lamoyi, E., Methods Enzymol. (1986) 121: 652-663; Rousseaux, J. etal, 
Methods Enzymol. (1986) 121 : 663-669; Bird, R. E. and Walker, B. W., Trends Biotechnol. 
(1991)9: 132-137). 
[0030] 

10 An antibody having exceedingly high agonistic activity can be prepared by reducing the 

molecular weight of a full-length antibody, particularly by converting it into an sc(Fv)2. 

In a preferred embodiment, the antibodies of the present invention comprise modified 
antibodies, such as chimeric antibodies and humanized antibodies that bind to Mpl. These 
modified antibodies can be produced by known methods. 
15 [0031] 

Chimeric antibodies are antibodies prepared by combining sequences derived from 
different animal species, and include for example, antibodies comprising the heavy chain and 
light chain variable regions of a murine antibody, and the heavy chain and light chain constant 
regions of a human antibody. Chimeric antibodies can be prepared by known methods. For 
20 example, a DNA encoding the V region of an antibody is linked to a DNA encoding the C region 
of a human antibody, and the construct is inserted into an expression vector and introduced into a 
host to produce chimeric antibodies. 
[0032] 

Humanized antibodies are also referred to as "reshaped human antibodies". Such a 
25 humanized antibody is obtained by transferring the complementarity-determining region (CDR) 
of an antibody derived from a non-human mammal, for example mouse, to the 
complementarity-determining region of a human antibody, and the general gene recombination 
procedure for this is also known (see European Patent Application No. 125023 and WO 
96/02576). 
30 [0033] 

Specifically, a DNA sequence designed to link a murine antibody CDR to the 
framework region (FR) of a human antibody can be synthesized by PCR, using primers prepared 
from several oligonucleotides containing overlapping portions of both CDR and FR terminal 
regions (see methods described in WO 98/13388). 
35 [0034] 

The human antibody framework region to be linked by CDR is selected in order to form 



23 JP 2004-071763 



a favorable antigen-binding site in the complementarity-determining region. Amino acids of 
the framework region in the antibody variable region may be substituted, as necessary, for the 
complementarity-determining region of the reshaped human antibody to form a suitable 
antigen-binding site (Sato, K. et al. 9 Cancer Res. (1993) 53: 851-856). 
5 [0035] 

The constant region of a human antibody is used as the constant region of a chimeric 
antibody or humanized antibody. For example, Cyl, Cy2, Cy3, and Cy4 can be used as the H 
chain, and Ck and CA, can be used as the L chain. The human antibody constant region may be 
modified to improve the antibody or the stability of the antibody production. 
10 [0036] 

Generally, chimeric antibodies comprise the variable region of an antibody from a 
non-human mammal and the constant region derived from a human antibody. On the other 
hand, humanized antibodies comprise the complementarity-determining region of an antibody 
from a non-human mammal, and the framework region and constant region derived from a 
1 5 human antibody. 

[0037] 

In addition, after a chimeric antibody or a humanized antibody is prepared, amino acids 
in the variable region (for example, FR) and the constant region may be replaced with other 
amino acids, and such. 

20 The origin of the variable regions in chimeric antibodies or that of the CDRs in 

humanized antibodies is not particularly limited, and may be derived from any type of animal. 
For example, sequences of murine antibodies, rat antibodies, rabbit antibodies, camel antibodies 
may be used. 

[0038] 

25 In general, it is difficult to chimerize or humanize an antibody without losing the 

agonistic activity of the original antibody. Nevertheless, the present invention succeeded in 
preparing humanized antibodies having agonistic activity equivalent to that of the original 
murine antibody. 
[0039] 

30 A preferred humanized antibody of the present invention is an antibody comprising a 

heavy chain variable region that comprises the amino acid sequence of SEQ ID NO: 229 
(humanized heavy chain sequence: hVB22B p-z VH), SEQ ID NO: 256 (humanized heavy chain 
sequence: hVB22B g-e VH), or SEQ ID NO: 262 (humanized heavy chain sequence: hVB22B e 
VH); or an antibody comprising a light chain variable region that comprises the amino acid 

35 sequence of SEQ ID NO: 238 (humanized light chain hVB22B p-z VL), or SEQ ID NO: 258 

(humanized light chain hVB22B g-e VL or hVB22B e VL). In particular, a preferred antibody

[0053] 

Chimeric antibodies and humanized antibodies exhibit lower antigenicity in the human 
body, and thus are expected to be useful when administered to humans for therapeutic purposes. 

In one embodiment, the preferred antibodies of the present invention include antibodies 
15 that bind to soluble Mpl. The term "soluble Mpl" herein refers to Mpl molecules excluding 
those expressed on the cell membrane. A specific example of a soluble Mpl is an Mpl lacking 
the entire or a portion of the transmembrane domain. The transmembrane domain of human 
Mpl corresponds to amino acids 492 to 513 in SEQ ID NO: 123. 

[0054] 

20 An antibody that binds to soluble recombinant Mpl can be used in detailed epitope 

analysis and kinetic analysis of receptor-ligand binding, as well as for assessing the blood 
concentration and dynamic behavior of the antibody in in vivo tests. 

In one embodiment, the preferred antibodies of the present invention include antibodies 
having binding activity against both human and monkey Mpl. Antibodies having agonistic 
25 activity to both human and monkey Mpl are expected to be highly useful since the dynamic 

behavior and in vivo effects of the antibody, which are generally difficult to determine in human 
body, can be examined with monkeys. 
[0055] 

The present invention also provides antibodies having agonistic activity to human Mpl 
30 and monkey Mpl. Such antibodies may also have binding activity or agonistic activity against 
Mpl from animals other than humans and monkeys (for example, mice). 
[0056] 

In addition, the antibodies of the present invention include antibodies with TPO 
agonistic activity (agonistic activity against Mpl) of EC50 = 100 nM or lower, preferably EC50 = 
35 30 nM or lower, more preferably EC50 = 10 nM or lower. 

[0057] 



29 JP 2004-071763 



The agonistic activity can be determined by methods known to those skilled in the art, 
for example, by the method described below. 

The sequences for human Mpl (Palacios et aL, Cell (1985) 41 : 727-734; GenBank Accession NO. 
NM_005373), cynomolgus monkey Mpl (SEQ ID NO: 157), and mouse Mpl (GenBank 
5 Accession NO. NM_010823) are already known. 

[0058] 

In addition, the present invention includes antibodies whose binding activities to soluble 
Mpl are KD = 1 0" 6 M or lower, preferably KD = 1 0" 7 M or lower, and more preferably KD = 1 0" 8 
M or lower. 

10 [0059] 

In the present invention, whether the binding activity of an antibody to soluble 
recombinant Mpl is KD = 1 0" 6 M or lower can be determined by methods known to those skilled 
in the art. For example, the activity can be determined using surface plasmon resonance with 
Biacore. Specifically, soluble MPL-Fc protein is immobilized onto sensor chips. Reaction 

1 5 rate constant can be determined by assessing the interaction between the antibody and the 
soluble Mpl-Fc protein. The binding activity can be evaluated by ELISA (enzyme -linked 
immunosorbent assays), EIA (enzyme immunoassays), RIA (radio immunoassays), or 
fluorescent antibody techniques. For example, in enzyme immunoassays, a sample containing a 
test antibody, such as purified antibody or culture supernatant of cells producing the test antibody, 

20 is added to a plate coated with an antigen to which the test antibody can bind. After incubating 
the plate with a secondary antibody labeled with an enzyme such as alkaline phosphatase, the 
plate is washed and an enzyme substrate such as p-nitrophenyl phosphate is added. The 
antigen-binding activity can then be evaluated by determining the absorbance. 
[0060] 

25 There is no specific limitation as to the upper limit of the binding activity; for example, 

the upper limit may be set within a technically feasible range by those skilled in the art. 
However, the technically feasible range may expand with the advancement of technology. 
[0061] 

In an embodiment, the preferred antibodies of the present invention include antibodies 
30 recognizing epitopes that are recognized by any one of the antibodies indicated in (I) to (XII)

[0075] 

Herein, the phrase "functionally equivalent" means that an antibody of interest has a 
35 biological or biochemical activity comparable to that of an antibody of the present invention. 
Such activities include, for example, binding activities and agonistic activities. 



36 



JP 2004-071763 



[0076] 

Methods for preparing polypeptides functionally equivalent to a certain polypeptide are 
well known to those skilled in the art, and include methods of introducing mutations into 
polypeptides. For example, those skilled in the art can prepare an antibody functionally 
5 equivalent to the antibodies of the present invention by introducing appropriate mutations into 
the antibody using site-directed mutagenesis (Hashimoto-Gotoh, T. et al Gene (1995) 152: 
271-275; Zoller, MJ, and Smith, M. Methods Enzymol. (1983) 100: 468-500; Kramer, W. et al, 
Nucleic Acids Res. (1984) 12: 9441-9456; Kramer, W. and Fritz HJ, Methods Enzymol. (1987) 
154: 350-367; Kunkel, TA, Proc. Natl. Acad. Sci. USA. (1985) 82: 488-492; Kunkel, Methods 

10 Enzymol. (1988) 85: 2763-2766), or such. Amino acid mutations may occur naturally. Thus, 
the present invention also comprises antibodies functionally equivalent to the antibodies of the 
present invention and comprising the amino acid sequences of these antibodies, in which one or 
more amino acids is mutated. Generally, the number of amino acids that are mutated is 50 
amino acids or less, preferably 30 or less, more preferably 10 or less (for example, five amino 

15 acids or less). 

[0077] 

An amino acid is preferably substituted for a different amino acid(s) that allows the 
properties of the amino acid side-chain to be conserved. Examples of amino acid side chain 
properties are: hydrophobic amino acids (A, I, L, M, F, P, W, Y, and V), hydrophilic amino acids 

20 (R, D, N, C, E, Q, G, H, K, S, and T), amino acids comprising the following side chains: aliphatic 
side chains (Q A, V, L, I, and P); hydroxyl -containing side chains (S, T, and Y); 
sulfur-containing side chains (C and M); carboxylic acid- and amide-containing side chains (D, 
N, E, and Q); basic side chains (R, K, and H); aromatic ring-containing side chains (H, F, Y, and 
W) (amino acids are represented by one-letter codes in parentheses). 

25 [0078] 

A polypeptide comprising a modified amino acid sequence, in which one or more amino 
acid residues is deleted, added, and/or replaced with other amino acids, is known to retain its 
original biological activity (Mark, D. F. et al, Proc. Natl. Acad. Sci. USA (1984) 81: 5662-5666; 
Zoller, M. J. & Smith, M. Nucleic Acids Research (1982) 10: 6487-6500; Wang, A. et al, 
30 Science 224: 1431-1433; Dalbadie-McFarland, G etal, Proc. Natl. Acad. Sci. USA (1982) 79: 
6409-6413). 

[0079] 

Fusion proteins containing antibodies that comprise the amino acid sequence of an 
antibody of the present invention, in which two or more amino acid residues have been added, 
35 are included in the present invention. The fusion protein results from a fusion between one of 
the above antibodies and a second peptide or protein, and is included in the present invention. 



37 



JP 2004-071763 



The fusion protein can be prepared by ligating a polynucleotide encoding an antibody of the 
present invention and a polynucleotide encoding a second peptide or polypeptide in frame, 
inserting this into an expression vector, and expressing the fusion construct in a host. Some 
techniques known to those skilled in the art are available for this purpose. The partner peptide 
5 or polypeptide to be fused with an antibody of the present invention may be a known peptide, for 
example, FLAG (Hopp, T. P. et aL, BioTechnology (1988) 6: 1204-1210), 6x His consisting of 
six His (histidine) residues, 1 Ox His, influenza hemagglutinin (HA), human c-myc fragment, 
VSV-GP fragment, pl8HIV fragment, T7-tag, HSV-tag, E-tag, SV40 T antigen fragment, Ick tag, 
a-tubulin fragment, B-tag, Protein C fragment. Other partner polypeptides to be fused with the 

10 antibodies of the present invention include, for example, GST (glutathione-S-transferase), HA 
(influenza hemagglutinin), immunoglobulin constant region, P-galactosidase, and MBP 
(maltose-binding protein). A polynucleotide encoding one of these commercially available 
peptides or polypeptides can be fused with a polynucleotide encoding an antibody of the present 
invention. The fusion polypeptide can be prepared by expressing the fusion construct. 

15 [0080] 

As described below, the antibodies of the present invention may differ in amino acid 
sequence, molecular weight, isoelectric point, presence/absence of sugar chains, and 
conformation depending on the cell or host producing the antibody, or purification method. 
However, a resulting antibody is included in the present invention, as long as it is functionally 
20 equivalent to an antibody of the present invention. For example, when an antibody of the 

present invention is expressed in prokaryotic cells, for example E. coli, a methionine residue is 
added to the N terminus of the original antibody amino acid sequence. Such antibodies are 
included in the present invention. 
[0081] 

25 An antibody that recognizes an epitope recognized by the antibody according to any one 

of (I) to (XII) indicated above is expected to have a high agonistic activity. Such antibodies can 
be prepared by methods known to those skilled in the art. The antibody can be prepared by, for 
example, determining the epitope recognized by the antibody according to any one of (I) to (XII) 
by conventional methods, and using a polypeptide comprising one of the epitope amino acid 

30 sequences as an immunogen. Alternatively, the antibody can be prepared by determining the 
epitopes of conventionally prepared antibodies and selecting an antibody that recognizes the 
epitope recognized by an antibody of any one of (I) to (XII). 
[0082] 

In the present invention, a particularly preferred antibody is an antibody that recognizes 
35 the epitope recognized by the antibody comprising the amino acid sequence of SEQ ID NO: 2. 
The antibody comprising the amino acid sequence of SEQ ED NO: 2 is predicted to recognize the 



38 JP 2004-071763 



region from Glu 26 to Leu 274, preferably the region from Ala 189 to Gly 245, more preferably 
the region from Gin 213 to Ala 23 1 of human Mpl. Thus, antibodies recognizing the region of 
amino acids 26 to 274, or amino acids 189 to 245, or amino acids 213 to 23 1 of human Mpl are 
also included in the present invention. 
5 [0083] 

Antibodies recognizing regions of amino acids 26 to 274, amino acids 189 to 245, or 
amino acids 213 to 231 of the human Mpl amino acid sequence (SEQ ID NO: 123) can be 
obtained by methods known to those skilled in the art. Such antibodies can be prepared by, for 
example, using a peptide comprising amino acids 26 to 274, amino acids 189 to 245, or amino 
10 acids 213 to 231 of the human Mpl amino acid sequence (SEQ ID NO: 123) as an immunogen. 
Alternatively, such antibodies can be prepared by determining the epitope of a conventionally 
prepared antibody and selecting an antibody that recognizes the same epitope recognized by an 
antibody of the present invention. 

[0084] 

1 5 The present invention provides antibodies described above in (I) to (XII). In an 

embodiment of the present invention, a preferred antibody is the one shown in (V), a more 
preferred antibody is the one shown in (VI), and a still more preferred is the one shown in (VIII). 
[0085] 

The present invention also provides vectors comprising polynucleotides encoding the 

20 antibodies of the present invention, or polynucleotides which hybridize under stringent 

conditions to the polynucleotides of the present invention and encode antibodies having activities 
equivalent to those of the antibodies of the present invention. The polynucleotides of the 
present invention are polymers comprising multiple bases or base pairs of deoxyribonucleic 
acids (DNA) or ribonucleic acids (RNA), and are not particularly limited, as long as they encode 

25 the antibodies of the present invention. They may also contain non-natural nucleotides. The 
polynucleotides of the present invention can be used to express antibodies using genetic 
engineering techniques. The polynucleotides of this invention can also be used as probes in the 
screening of antibodies functionally equivalent to the antibodies of the present invention. 
Specifically, DNAs that hybridize under stringent conditions to a polynucleotide encoding an 

30 antibody of the present invention, and encode antibodies having activity equivalent to those of 
the antibodies of the present invention can be obtained by techniques such as hybridization and 
gene amplification (for example, PCR), using a polynucleotide of the present invention or a 
portion thereof as a probe. Such DNAs are also included in the polynucleotides of the present 
invention. Hybridization techniques are well known to those skilled in the art (Sambrook, J et 

35 al , Molecular Cloning 2nd ed., 9.47-9.58, Cold Spring Harbor Lab. press, 1 989). Such 
hybridization conditions include, for example, conditions of low stringency. Examples of 



39 JP 2004-071763 



conditions of low stringency include post-hybridization washing in 0.1 x SSC and 0.1% SDS at 
42°C, and preferably in 0.1 x SSC and 0.1% SDS at 50°C. More preferable hybridization 
conditions include those of high stringency. Highly stringent conditions include, for example, 
washing in 5x SSC and 0.1% SDS at 65°C. In these conditions, the higher the temperature, the 
5 higher the expectation of efficiently obtaining polynucleotides with a high homology. However, 
several factors, such as temperature and salt concentration, can influence hybridization 
stringency, and those skilled in the art can suitably select these factors to accomplish similar 
stringencies. 

[0086] 

1 0 Antibodies that are encoded by polynucleotides obtained by the hybridization and gene 

amplification techniques, and are functionally equivalent to the antibodies of the present 
invention generally exhibit high homology to the antibodies of the this invention at the amino 
acid level. The antibodies of the present invention include antibodies that are functionally 
equivalent to the antibodies of the present invention, and exhibit high amino acid sequence 

15 homology to the antibodies of this invention. The term "high homology" generally means 
identity at the amino acid level of at least 50% or higher, preferably 75% or higher, more 
preferably 85% or higher, still more preferably 95% or higher. Polypeptide homology can be 
determined by the algorithm described in the report: Wilbur, W. J. and Lipman, D. J. Proc. Natl. 
Acad. Sci. USA (1983) 80: 726-730. 

20 [0087] 

When E. coli is used as a host, there is no particular limitation as to the type of vector of 
the present invention, as long as the vector contains an "ori" responsible for its replication in E. 
coli and a marker gene. The "ori" ensures the amplification and mass production of the vector 
in E. coli (for example, JM109, DH5a, HB101, and XL 1 Blue). The marker gene is used to 

25 select the E. coli transformants (for example, a drug resistance gene selected by an appropriate 
drug such as ampicillin, tetracycline, kanamycin, and chloramphenicol). The vectors include, 
for example, Ml 3 vectors, pUC vectors, pBR322, pBluescript, and pCR-Script. In addition to 
the above vectors, for example, pGEM-T, pDIRECT, and pT7 can also be used for the 
subcloning and excision of cDNAs. 

30 [0088] 

An expression vector is especially useful for the type of vectors of the present invention. 
When an expression vector is expressed, for example, in E. coli, it should have the above 
characteristics in order to be amplified in E. coli. Additionally, when E. coli, such as JM109, 
DH5a, HB101, or XLl-Blue are used as the host cell, the vector preferably has a promoter, for 
35 example, lacZ promoter (Ward et al Nature (1989) 341 : 544-546; FASEB J. (1992) 6: 

2422-2427), araB promoter (Better et al Science (1988) 240: 1041-1043), or T7 promoter, that 



40 JP 2004-071763 



allows efficient expression of the desired gene in E. coli. Other examples of the vectors include 
pGEX-5X-l (Pharmacia), "QIAexpress system" (QIAGEN), pEGFP, and pET (where BL21, a 
strain expressing T7 RNA polymerase, is preferably used as the host). 
[0089] 

5 Furthermore, the vector may comprise a signal sequence for polypeptide secretion. 

When producing polypeptides into the periplasm of E. coli, the pelB signal sequence (Lei, S. P. 
et ah J. Bacteriol. (1987) 169: 4379) may be used as a signal sequence for polypeptide secretion. 
For example, calcium chloride methods or electroporation methods may be used to introduce the 
vector into a host cell. 
10 [0090] 

In addition to E. coli, expression vectors derived from mammals (e.g., pCDNA3 
(Invitrogen), pEGF-BOS (Nucleic Acids Res. (1990) 18 (17): 5322), pEF, pCDM8), insect cells 
(e.g., "Bac-to-BAC baculovirus expression system" (GIBCOBRL), pBacPAK8), plants (e.g., 
pMHl, pMH2), animal viruses (e.g., pHSV, pMV, pAdexLcw), retroviruses (e.g., pZIPneo), 
15 yeasts (e.g., "Pichia Expression Kit" (Invitrogen), pNVll, SP-Q01), and Bacillus subtilis (e.g., 
pPL608, pKTH50) may also be used as a vector of the present invention. 
[0091] 

In order to express proteins in animal cells such as CHO, COS, and NIH3T3 cells, the 
vector preferably has a promoter necessary for expression in such cells, for example, an SV40 

20 promoter (Mulligan et ah, Nature (1979) 277: 108), MMLV-LTR promoter, EFla promoter 

(Mizushima et ah, Nucleic Acids Res. (1990) 18: 5322), CMV promoter, etc.). It is even more 
preferable that the vector also carries a marker gene for selecting transformants (for example, a 
drug-resistance gene selected by a drug such as neomycin and G418). Examples of vectors 
with such characteristics include pMAM, pDR2, pBK-RSV, pBK-CMV, pOPRSV, and pOP13, 

25 and such. 

[0092] 

In addition, to stably express a gene and amplify the gene copy number in cells, CHO 
cells that are defective in the nucleic acid synthesis pathway are introduced with a vector 
containing a DHFR gene (for example, pCHOI) to compensate for the defect, and the copy 

30 number is amplified using methotrexate (MTX). Alternatively, a COS cell, which carries an 
SV40 T antigen-expressing gene on its chromosome, can be transformed with a vector 
containing the S V40 replication origin (for example, pcD) for transient gene expression. The 
replication origin may be derived from polyoma virus, adenovirus, bovine papilloma virus 
(BPV), and such. Furthermore, to increase the gene copy number in host cells, the expression 

35 vector may contain, as a selection marker, aminoglycoside transferase (APH) gene, thymidine 
kinase (TK) gene, E. coli xanthine guanine phosphoribosyl transferase (Ecogpt) gene, 



41 JP 2004-071763 



dihydrofolate reductase (dhfr) gene, and such. 
[0093] 

Next, the vector is introduced into a host cell. The host cells into which the vector is 
introduced are not particularly limited, for example, E. coli and various animal cells are available 
5 for this purpose. The host cells may be used, for example, as a production system to produce 
and express the antibodies of the present invention. In vitro and in vivo production systems are 
available for polypeptide production systems. Production systems that use eukaryotic cells or 
prokaryotic cells are examples of in vitro production systems. 
[0094] 

1 0 Eukaryotic cells that can be used are, for example, animal cells, plant cells, and fungal 

cells. Known animal cells include: mammalian cells, for example, CHO (J. Exp. Med. (1995) 
108: 945), COS, 3T3, myeloma, BHK (baby hamster kidney), HeLa, Vero, amphibian cells such 
as Xenopus laevis oocytes (Valle, et al. } Nature (1981) 291: 358-340), or insect cells (e.g., Sf9, 
Sf21, and Tn5). In the present invention, CHO-DG44, CHO-DXB11, COS7 cells, and BHK 

15 cells can be suitably used. Among animal cells, CHO cells are particularly favorable for 
large-scale expression. Vectors can be introduced into a host cell by, for example, calcium 
phosphate methods, the DEAE-dextran methods, methods using cationic liposome DOTAP 
(Boehringer-Mannheim), electroporation methods, lipofection methods. 
[0095] 

20 Plant cells include, for example, Nicotiana taZxzcwm-derived cells known as a protein 

production system. Calluses may be cultured from these cells. Known fungal cells include 
yeast cells, for example, genus Saccharomyces such as Saccharomyces cerevisiae and 
Saccharomyces pombe; and filamentous fungi, for example, genus Aspergillus such as 
Aspergillus niger. 

25 [0096] 

Bacterial cells can be used in the prokaryotic production systems. Examples of 
bacterial cells include E. coli (for example, JM109, DH5<x, HB101 and such); and Bacillus 
subtilis. 

[0097] 

30 Next, the above host cells are cultured. Antibodies can be obtained by transforming 

the cells with a polynucleotide of interest and in vitro cultuiing of these transformants. 
Transformants can be cultured using known methods. For example, DMEM, MEM, RPMI 
1640, or IMDM may be used as the culture medium for animal cells, and may be used with or 
without serum supplements such as FBS or fetal calf serum (FCS). Serum-free cultures are also 

35 acceptable. The preferred pH is about 6 to 8 during the course of culturing. Incubation is 

carried out typically at a temperature of about 30 to 40°C for about 15 to 200 hours. Medium is 



42 



JP 2004-071763 



exchanged, aerated, or agitated, as necessary. 
[0098] 

On the other hand, production systems using animal or plant hosts may be used as 
systems for producing polypeptides in vivo. For example, a polynucleotide of interest is 
5 introduced into an animal or plant and the polypeptide is produced in the body of the animal or 
plant and then recovered. The "hosts" of the present invention includes such animals and 
plants. 

[0099] 

Animals to be used for the production system include mammals or insects. Mammals 
10 such as goats, pigs, sheep, mice, and cattle may be used (Vicki Glaser SPECTRUM 

Biotechnology Applications (1993)). Alternatively, the mammals may be transgenic animals. 
[0100] 

For example, a polynucleotide of interest is prepared as a fusion gene with a gene 
encoding a polypeptide specifically produced in milk, such as the goat P-casein gene. DNA 
15 fragments containing the fusion gene are injected into goat embryos, which are then introduced 
back to female goats. The desired antibody can be obtained from milk produced by the 
transgenic goats, which are bom from the goats that received the embryos, or from their 
offspring. Appropriate hormones may be administered to increase the volume of milk 
containing the antibody produced by the transgenic goats (Ebert, K.M. et aL, Bio/Technology 
20 (1994) 12:699-702). 

[0101] 

Insects, such as silkworms, may also be used. Baculoviruses carrying a polynucleotide 
encoding an antibody of interest can be used to infect silkworms, and the antibody of interest can 
be obtained from the body fluids (Susumu, M. et al , Nature (1 985) 315: 592-594). 
25 [0102] 

Plants used in the production system include, for example, tobacco. When tobacco is 
used, a polynucleotide encoding an antibody of interest is inserted into a plant expression vector, 
for example, pMON 530, and then the vector is introduced into a bacterium, such as 
Agrobacterium tumefaciens . The bacteria are then used to infect tobacco such as Nicotiana 
30 tabacum, and the desired antibodies can be recovered from the leaves (Julian K.-C. Ma et al. 9 Eur. 
J. Immunol. (1994) 24: 131-138). 
[0103] 

The resulting antibody may be isolated from the inside or outside (such as the medium) 
of host cells, and purified as a substantially pure and homogenous antibody. Methods are not 
35 limited to any specific method and any standard method for isolating and purifying antibodies 
may be used. Polypeptides may be isolated and purified, by selecting an appropriate 



43 



JP 2004-071763 



combination of, for example, chromatographic columns, filtration, ultrafiltration, salting out, 
solvent precipitation, solvent extraction, distillation, immunoprecipitation, SDS-polyacrylamide 
gel electrophoresis, isoelectric focusing, dialysis, recrystallization, and others. 
[0104] 

Chromatographies include, for example, affinity chromatographies, ion exchange 
chromatographies, hydrophobic chromatographies, gel filtrations, reverse-phase 
chromatographies, and adsorption chromatographies (Strategies for Protein Purification and 
Characterization: A Laboratory Course Manual. Ed Daniel R. Marshak et aL, Cold Spring Harbor 
Laboratory Press, 1996). These chromatographies can be carried out using liquid phase 
chromatographies such as HPLC and FPLC. Examples of the affinity chromatography columns 
include protein A columns and protein G columns. Examples of the proteins A columns include 
Hyper D, POROS, and Sepharose F. F. (Pharmacia). 

[0105] 

An antibody can be modified freely and peptide portions deleted by treating the 
antibody with an appropriate protein modifying enzyme before or after antibody purification. 
Such protein modifying enzymes include, for example, trypsins, chymotrypsins, lysyl 
endopeptidases, protein kinases, and glucosidases. 

[0106] 

Antibodies that bind to Mpl can be prepared by methods known to those skilled in the 

art. 

For example, monoclonal antibody-producing hybridomas can be essentially generated 
by known technologies as follows: immunizing animals with Mpl proteins or Mpl-expressing 
cells as sensitized antigens using conventional immunological methods; fusing the obtained 
immunocytes with known parental cells by conventional cell fusion methods; and screening for 
monoclonal antibody-producing cells by conventional methods. 

[0107] 

Specifically, monoclonal antibodies can be prepared by the method below. 

First, Mpl protein, which is used as a sensitized antigen for preparing antibodies, is 
prepared by expressing the Mpl gene/amino acid sequence (GenBank accession number: 
NM_005373). More specifically, the gene sequence encoding Mpl is inserted into a known 
expression vector, which is then transfected into an appropriate host cell. The subject human 
Mpl protein is purified from the host cell or culture supernatant using known methods. 

[0108] 

The purified Mpl protein is then used as a sensitized antigen. Alternatively, a partial 
Mpl peptide may be used as a sensitized antigen. In this case, the partial peptide can also be 
chemically synthesized based on the amino acid sequence of human Mpl. 



44 JP 2004-071763 



[0109] 

The epitopes of Mpl molecule that are recognized by an anti-Mpl antibody of the 
present invention are not limited to a particular epitope, and may be any epitope on the Mpl 
molecule. Thus, any fragment can be used as an antigen for preparing anti-Mpl antibodies of 
5 the present invention, as long as the fragment comprises an epitope of the Mpl molecule. 

[0110] 

There is no limitation as to the type of mammalian species to be immunized with the 
sensitized antigen. However, a mammal is preferably selected based on its compatibility with 
the parental cell to be used in cell fusion. Generally, rodents (for example, mice, rats, and 
1 0 hamsters), rabbits, and monkeys can be used. 

[0111] 

Animals can be immunized with a sensitized antigen by known methods such as a 
routine method of injecting a sensitized antigen into a mammal intraperitoneally or 
subcutaneously. Specifically, the sensitized antigen is diluted appropriately with 

1 5 phosphate-buffered saline (PBS), physiological saline and such, and then suspended. An 

adequate amount of a conventional adjuvant, for example, Freund's complete adjuvant, is mixed 
with the suspension, as necessary. An emulsion is then prepared for administering to a mammal 
several times over a 4- to 2 1 -day interval. An appropriate carrier may be used for the sensitized 
antigen in immunization. 

20 [0112] 

A mammal is immunized as described above. After a titer increase of target antibody 
in the serum is confirmed, immunocytes are collected from the mammal and then subjected to 
cell fusion. Spleen cells are the preferred immunocytes. 

[0113] 

25 Mammalian myeloma cells are used as the parental cells to be fused with the above 

immunocytes. Preferable myeloma cells to be used include various known cell lines, for 
example, P3 (P3x63Ag8.653) (Kearney JF, etal, J. Immnol. (1979) 123: 1548-1550), 
P3x63Ag8U.l (Yelton DE, et aL, Current Topics in Microbiology and Immunology (1978) 81: 
1-7), NS-1 (Kohler, G and Milstein, C. Eur. J. Immunol. (1976) 6: 511-519), MPC-11 (Margulies, 

30 D. H. et aL, Cell (1976) 8: 405-415), SP2/0 (Shulman, M. et aL, Nature (1978) 276: 269-270), 
FO (deSt. Groth, S. F. et aL, J. Immunol. Methods (1980) 35: 1-21), S194 (Trowbridge, L S., J. 
Exp. Med. (1978) 148: 313-323), and R210 (Galfre, G etaL, Nature (1979) 277: 131-133). 
[0114] 

Cell fusions between the immunocytes and the myeloma cells as described above can be 
35 essentially carried out using known methods, for example, a method by Kohler and Milstein 
(Kohler, G and Milstein, C, Methods EnzymoL (1981) 73: 3-46). 



45 JP 2004-071763 



[0115] 

More specifically, the above-described cell fusions are carried out, for example, in a 
conventional culture medium in the presence of a cell fusion-promoting agent. The 
fusion-promoting agents include, for example, polyethylene glycol (PEG) and Sendai virus 
5 (HVJ). If required, an auxiliary substance such as dimethyl sulfoxide may also be added to 
improve fusion efficiency. 
[0116] 

The ratio of immunocytes to myeloma cells may be determined at one's own discretion, 
preferably, for example, one myeloma cell for every one to ten immunocytes. Culture media to 
10 be used for the above cell fusions include, for example, media that are suitable for the growth of 
the above myeloma cell lines, such as RPMI 1640 media and MEM media, and other 
conventional culture media used for this type of cell culture. In addition, serum supplements 
such as fetal calf serum (FCS) may also be used in combination. 

[0117] 

15 Cell fusion is carried out as follows. As described above, predetermined amounts of 

immunocytes and myeloma cells are mixed well in the culture medium. PEG solution (for 
example, mean molecular weight of about 1,000-6,000) pre-heated to 37°C is added to the cell 
suspension typically at a concentration of 30% to 60% (w/v), and mixed to produce fused cells 
(hybridomas). Then, an appropriate culture medium is successively added to the mixture, and 

20 the sample is centrifuged to remove supernatant. This treatment is repeated several times to 
remove the unwanted cell fusion-promoting agent and others that are unfavorable to hybridoma 
growth. 

[0118] 

Screening of the resulting hybridomas can be carried out by culturing them in a 
25 conventional selective medium, for example, hypoxanthine, aminopterin, and thymidine (HAT) 
medium. Culturing in the above-descried HAT medium is continued for a period long enough 
(typically, for several days to several weeks) to kill cells (non-fused cells) other than the desired 
hybridomas. Then, hybridomas are screened for single-cell clones capable of producing the 
target antibody by conventional limiting dilution methods. 
30 [0119] 

In addition to the method for preparing the above-descried hybridomas by immunizing 
non-human animals with antigens, preferred human antibodies having binding activity to Mpl 
can also be obtained by: sensitizing human lymphocytes with Mpl in vitro; and fusing the 
sensitized lymphocytes with human myeloma cells capable of dividing permanently (see, 
35 Japanese Patent Application Kokoku Publication No. (JP-B) H01-59878 (examined, approved 
Japanese patent application published for opposition)). Alternatively, it is possible to obtain 



46 JP 2004-071763 



human antibodies against Mpl from immortalized cells producing anti-Mpl antibodies. In this 
method, the cells producing anti-Mpl antibodies are prepared by administering Mpl as an antigen 
to transgenic animals comprising a repertoire of the entire human antibody genes (see, WO 
94/25585, WO 93/12227, WO 92/03918, and WO 94/02602). 
5 [0120] 

The monoclonal antibody-producing hybridomas thus prepared can be passaged in a 
conventional culture medium, and stored in liquid nitrogen over long periods of time. 
[0121] 

Monoclonal antibodies can be prepared from the above-described hybridomas by, for 
1 0 example, a routine procedure of culturing the hybridomas and obtaining antibodies from the 
culture supernatants. Alternatively, monoclonal antibodies can be prepared by injecting the 
hybridomas into a compatible mammal; growing these hybridomas in the mammal; and 
obtaining antibodies from the mammal's ascites. The former method is suitable for preparing 
highly purified antibodies, while the latter is suitable for preparing antibodies on a large scale. 
15 [0122] 

Recombinant antibodies can also be prepared by: cloning an antibody gene from a 
hybridoma; inserting the gene into an appropriate vector; introducing the vector into a host; and 
producing the antibodies by using genetic recombination techniques (see, for example, 
Vandamme, A. M. etal, Eur. J. Biochem. (1990) 192: 767-775). 
20 [0123] 

Specifically, an mRNA encoding the variable (V) region of anti-Mpl antibody is isolated 
from hybridomas producing the anti-Mpl antibodies. For mRNA isolation, total RNAs are first 
prepared by conventional methods such as guanidine ultracentrifixgation methods (Chirgwin, J. 
M. et al, Biochemistry (1979) 18: 5294-5299), or acid guanidinium 
25 thiocyanate-phenol-chloroform (AGPC) methods (Chomczynski, R et a/., Anal. Biochem. (1987) 
162: 156-159), and then the target mRNA is prepared using an mRNA Purification Kit 
(Pharmacia) and such. Alternatively, the mRNA can be directly prepared using the QuickPrep 
mRNA Purification Kit (Pharmacia). 

[0124] 

30 A cDNA of the antibody V region is synthesized from the resulting mRNA using reverse 

transcriptase. cDNA synthesis is carried out using the AMV Reverse Transcriptase First-strand 
cDNA Synthesis Kit (Seikagaku Co.), or such. Alternatively, cDNA can be synthesized and 
amplified by the 5'-RACE method (Frohman, M. A. et of., Proc. Natl. Acad. Sci. USA (1988) 85: 
8998-9002; Belyavsky, A. et aL, Nucleic Acids Res. (1989) 17: 2919-2932) using the 5'-Ampli 

35 FINDER RACE Kit (Clontech) and PCR. 

[0125] 



47 



JP 2004-071763 



Target DNA fragments are purified from the obtained PCR products and then ligated 
with vector DNAs to prepare recombinant vectors. The vectors are introduced into E. coli and 
such, and colonies are selected for preparing the recombinant vector of interest. The target 
DNA nucleotide sequence is then confirmed by conventional methods such as the 
5 dideoxynucleotide chain termination method. 

Once a DNA encoding the V region of target anti-Mpl antibody is obtained, the DNA is 
inserted into an expression vector which comprises a DNA encoding the constant region (C 
region) of a desired antibody. 

[0126] 

10 The method for producing anti-Mpl antibodies to be used in the present invention 

typically comprises the steps of: inserting an antibody gene into an expression vector, so that the 
gene is expressed under the regulation of expression regulatory regions, such as enhancer and 
promotor; and transforming host cells with the resulting vectors to express antibodies. 
[0127] 

1 5 For expressing the antibody gene, polynucleotides encoding H chain and L chain, 

respectively, are inserted into separate expression vectors and co-transfected into a host cell. 
Alternatively, polynucleotides encoding both H chain and L chain are inserted into a single 
expression vector and transfected into a host cell (see WO 94/11523). 
[0128] 

20 The term "agonistic activity" refers to an activity to induce changes in some biological 

activities through signal transduction into cells and such, due to the binding of an antibody to a 
receptor antigen. The biological activities include, for example, proliferation-promoting 
activities, proliferation activities, viability activities, differentiation-inducing activities, 
differentiation activities, transcriptional activities, membrane transport activities, binding 

25 activities, proteolytic activities, phosphorylation/dephosphorylation activities, 

oxidation/reduction activities, transfer activities, nucleolytic activities, dehydration activities, 
cell death-inducing activities, and apoptosis-inducing activities, but is not limited thereto. 
[0129] 

The term "agonistic activity against Mpl" typically refers to the activity of promoting 
30 the differentiation of megakaryocytes or their parental hemopoietic stem cells into platelets, or 
the activity of stimulating platelet proliferation. 

Agonistic activity can be assayed by methods known to those skilled in the art. The 
agonistic activity may be determined using the original activity or a different activity as an 
indicator. 
35 [0130] 

For example, agonistic activity can be determined by a method using cell growth as an 



48 



JP 2004-071763 



indicator as described in Examples. More specifically, an antibody whose agonistic activity is 
to be determined is added to cells which proliferate in an agonist-dependent manner, followed by 
incubation of the cells. Then, a reagent such as WST-8 which shows a coloring reaction at 
specific wavelengths depending on the viable cell count, is added to the culture and absorbance 
5 is measured. The agonistic activity can be determined using the measured absorbance as an 
indicator. 

[0131] 

Cells that proliferate in an agonist-dependent manner can also be prepared by methods 
known to those skilled in the art. For example, when the antigen is a receptor capable of 

1 0 transducing cell growth signals, cells expressing the receptor may be used. Alternatively, when 
the antigen is a receptor that cannot transduce signals, a chimeric receptor consisting of the 
intracellular domain of a receptor that transduces cell growth signals and the extracellular 
domain of a receptor that does not transduce cell growth signals can be prepared for cellular 
expression. Receptors that transduce cell growth signals include, for example, G-CSF receptors, 

15 mpl, neu, GM-CSF receptors, EPO receptors, c-kit, and FLT-3. Cells that can be used to 

express a receptor include, for example, BaF3, NFS60, FDCP-1, FDCP-2, CTLL-2, DA-1, and 
KT-3. 

[0132] 

There is no limitation as to the type of detection indicators to be used for determining 

20 agonistic activity, as long as the indicator can monitor quantitative and/or qualitative changes. 
For example, it is possible to use cell-free assay indicators, cell-based assay indicators, 
tissue-based assay indicators, and in vivo assay indicators. Indicators that can be used in 
cell-free assays include enzymatic reactions, quantitative and/or qualitative changes in proteins, 
DNAs, or RNAs. Such enzymatic reactions include, for example, amino acid transfers, sugar 

25 transfers, dehydrations, dehydrogenations, and substrate cleavages. Alternatively, protein 

phosphorylations, dephosphorylations, dimerizations, multimerizations, hydrolyses, dissociations 
and such; DNA or RNA amplifications, cleavages, and extensions can be used as the indicator in 
cell-free assays. For example, protein phosphorylations downstream of a signal transduction 
pathway may be used as a detection indicator. Alterations in cell phenotype, for example, 

30 quantitative and/or qualitative alterations in products, alterations in growth activity, alterations in 
cell number, morphological alterations, or alterations in cellular properties, can be used as the 
indicator in cell-based assays. The products include, for example, secretory proteins, surface 
antigens, intracellular proteins, and mRNAs. The morphological alterations include, for 
example, alterations in dendrite formation and/or dendrite number, alteration in cell flatness, 

35 alteration in cell elongation/axial ratio, alterations in cell size, alterations in intracellular 

structure, heterogeneity/homogeneity of cell populations, and alterations in cell density. Such 



49 JP 2004-071763 



morphological alterations can be observed under a microscope. Cellular properties to be used 
as the indicator include anchor dependency, cytokine-dependent response, hormone dependency, 
drug resistance, cell motility, cell migration activity, pulsatory activity, and alteration in 
intracellular substances. Cell motility includes cell infiltration activity and cell migration 
5 activity. The alterations in intracellular substances include, for example, alterations in enzyme 
activity, mRNA levels, levels of intracellular signaling molecules such as Ca 2+ and cAMP, and 
intracellular protein levels. When a cell membrane receptor is used, alterations in the cell 
proliferating activity induced by receptor stimulation can be used as the indicator. The 
indicators to be used in tissue-based assays include functional alterations adequate for the subject 
10 tissue. In in vivo assays, alterations in tissue weight, alterations in the blood system (for 

example, alterations in blood cell counts, protein contents, or enzyme activities), alterations in 
electrolyte levels, and alterations in the circulating system (for example, alterations in blood 
pressure or heart rate). 
[0133] 

1 5 The methods for measuring such detection indices are not particularly limited. For 

example, absorbance, luminescence, color development, fluorescence, radioactivity, fluorescence 
polarization, surface plasmon resonance signal, time-resolved fluorescence, mass, absorption 
spectrum, light scattering, and fluorescence resonance energy transfer may be used. These 
measurement methods are known to those skilled in the art and may be selected appropriately 

20 depending on the purpose. For example, absorption spectra can be obtained by using a 
conventional photometer, plate reader, or such; luminescence can be measured with a 
luminometer or such; and fluorescence can be measured with a fluorometer or such. Mass can 
be determined with a mass spectrometer. Radioactivity can be determined with a device such 
as a gamma counter depending on the type of radiation. Fluorescence polarization can be 

25 measured with BEACON (TaKaRa). Surface plasmon resonance signals can be obtained with 
BIACORE. Time-resolved fluorescence, fluorescence resonance energy transfer, or such can 
be measured with ARVO or such. Furthermore, a flow cytometer can also be used for 
measuring. It is possible to use one of the above methods to measure two or more different 
types of detection indices. A greater number of detection indices may also be examined by 

30 using two or more measurement methods simultaneously and/or consecutively. For example, 

fluorescence and fluorescence resonance energy transfer can be measured at the same time with a 
fluorometer.

for the platelet count to recover to the normal level can be shortened by administering an 
antibody of the present invention after donation of platelet components. The amount of platelet 
components at the time of blood collection can be increased by pre-administering an antibody of 
the present invention. 
5 [0135] 

When used as pharmaceutical compositions, the antibodies of the present invention can 
be formulated by methods known to those skilled in the art. For example, the antibodies can be 
administered parenterally by injection of a sterile solution or suspension in water or other 
pharmaceutically acceptable solvents. For example, the antibodies can be formulated by 

1 0 appropriately combining with pharmaceutically-acceptable carriers or solvents, specifically, 

sterile water or physiological saline, vegetable oils, emulsifiers, suspending agents, surfactants, 
stabilizers, flavoring agents, excipients, vehicles, preservatives, binding agents, and such, and 
mixing at a unit dosage and form required by accepted pharmaceutical implementations. In 
such formulations, the amount of the thus obtained active ingredient should be within the 

1 5 required range . 

[0136] 

A sterile composition to be injected can be formulated using a vehicle such as distilled 
water used for injection, according to standard protocols. 

Aqueous solutions used for injections include, for example, physiological saline and 
20 isotonic solutions comprising glucose or other adjunctive agents such as D-sorbitol, D-mannose, 
D-mannitol, and sodium chloride. They may also be combined with an appropriate solubilizing 
agent such as alcohol, specifically, ethanol, polyalcohol such as propylene glycol or polyethylene 
glycol, or non-ionic detergent such as polysorbate 80™ or HCO-50, as necessary. 

[0137] 

25 Oil solutions include sesame oils and soybean oils, and can be combined with 

solubilizing agents such as benzyl benzoate or benzyl alcohol. Injection solutions may also be 
formulated with buffers, for example, phosphate buffers or sodium acetate buffers; analgesics, 
for example, procaine hydrochloride; stabilizers, for example, benzyl alcohol or phenol; or 
anti-oxidants. The prepared injections are typically aliquoted into appropriate ampules. 

30 [0138] 

The administration is preferably carried out parenterally, specifically, by injection, 
intranasal administration, intrapulmonary administration, percutaneous administration, or such. 
Injections include, for example, intravenous injections, intramuscular injections, intraperitoneal 
injections, and subcutaneous injections. The injection solutions can be also administered 

35 systemically or locally.

The administration methods can be selected properly according to the patient's age, 
condition, and such. The applied dose of a pharmaceutical composition comprising an antibody 
or polynucleotide encoding the antibody may be, for example, in the range of 0.0001 to 1,000 
mg/kg body weight. Alternatively, the dosage may be, for example, in the range of 0.001 to 
5 100,000 mg/kg body weight. However, the dosage is not restricted to the values described 
above. The dosage and administration methods depend on the patient's weight, age, and 
condition, and are appropriately selected by those skilled in the art.

10 The present invention is specifically illustrated below with reference to Examples, but it 

is not to be construed as being limited thereto. 
[0141] 

[Example 1] Preparation of anti-human Mpl antibodies 

1.1 Establishment of Mpl-expressing BaF3 cell lines 
15 BaF3 cell lines expressing the full-length Mpl gene were established to obtain cell lines 

that proliferate in a TPO-dependent manner. 

A full-length human Mpl cDNA (Palacios, R. et ai, Cell (1985) 41 : 727-734) (GenBank 

accession NO. NM_005373) was amplified by PCR. The cDNA was cloned into a pCOS2 

expression vector to construct pCOS2-hMplfull. The expression vector pCOS2 was 
20 constructed by removing the DHFR gene expression region from pCHOI (Hirata, Y. et ai, FEBS 

Letter (1994) 356: 244-248), where the expression region of the neomycin resistance gene 

HEF-VH-gyl (Sato, K. et al, Mol Immunol. (1994) 31: 371-381) is inserted. 
[0142] 

The cynomolgus monkey Mpl cDNA (SEQ ID NO: 164) was cloned from total RNA 
25 extracted from the bone marrow cells of cynomolgus monkey, using a SMART RACE cDNA 
Amplification Kit (Clontech). The resulting cynomolgus monkey cDNA was. inserted into 
pCOS2 to construct pCOS2-monkeyMplfull. 

Then, the full-length mouse Mpl cDNA (GenBank accession NO. NM_0 10823) was 
amplified by PCR, and inserted into pCOS2 to construct pCOS2-mouseMplfull. 
30 [0143] 

Each vector (20 jig) prepared as described above was mixed with BaF3 cells (1 x 10 7 
cells/mL) suspended in PBS in Gene Pulser cuvettes. This mixture was then pulsed at 0.33 kV 
and 950 jxFD using a Gene Pulser II (Bio-Rad). The BaF3 cells introduced with the above 
DNAs by electroporation were added to RPMI 1640 medium (Invitrogen) containing 1 ng/mL 
35 mouse interleukin 3 (hereinafter abbreviated as mIL-3; Peprotech), 500 ng/mL Geneticin 

(Invitrogen), and 10% FBS (Invitrogen), and selected to establish a human Mpl-expressing BaF3 



JP 2004-071763 



cell line (hereinafter abbreviated as "BaF3-human Mpl"), monkey Mpl-expressing BaF3 cell line 
(hereinafter abbreviated as BaF3 -monkey Mpl), and mouse Mpl-expressing BaF3 cell line 
(hereinafter abbreviated as "BaF3 -mouse Mpl"). Following selection, these cells were cultured 
and maintained in RPMI 1640 containing 1 ng/mL rhTPO (R&D) and 10% FBS. 
5 [0144] 

1 .2 Establishment of Mpl-expressing CHO cell lines 

CHO cell lines expressing the full-length Mpl gene were established to obtain cell lines 
to be used for assessing binding activity by flow cytometry. 

First, the DHFR gene expression site from pCHOI was inserted into pCXN2 (Niwa, H. 

1 0 et al , Gene ( 1 99 1 ) 1 08 : 1 93 - 1 99) at the Hindlll site to prepare a pCXND3 expression vector. 
The respective Mpl genes were amplified by PCR using pCOS2-hMplfull, 
pCOS2-monkeyMplfull, and pCOS2-mouseMplfiill as templates, and primers with a His-tag 
sequence. The PCR products were cloned into pCXND3 to construct pCXND3-hMpl-His, 
pCXND3-monkey Mpl-His, and pCXND3 -mouse Mpl-His, respectively. 

15 [0145] 

Vectors thus prepared (25 |j,g each) were mixed with a PBS suspension of CHO-DG44 

7 - 

cells (1x10 cells/mL) in Gene Pulser cuvettes. The mixture was then pulsed at 1 .5 kV and 25 
^iFD using Gene Pulser II (Bio-Rad). The CHO cells introduced with these DNAs by 
electroporation were added to CHO-S-SFMII medium (Invitrogen) containing 500 p,g/mL 
20 Geneticin and lx HT (Invitrogen). A human Mpl-expressing CHO cell line (hereinafter 
abbreviated as "CHO-human Mpl"), monkey Mpl-expressing CHO cell line (hereinafter 
abbreviated as "CHO-monkey Mpl"), and mouse Mpl-expressing CHO cell line (hereinafter 
abbreviated as "CHO-mouse Mpl") were established through selection. 
[0146] 

25 1 .3 Preparation of soluble human Mpl protein 

To prepare soluble human Mpl protein, an expression system using insect Sf9 cells for 
production and secretion of the protein was constructed as described below. 

A DNA construct encoding the extracellular region of human Mpl (Gin 26 to Tip 491) 
with a downstream FLAG tag was prepared. The construct was inserted into a pBACSurf-1 
30 Transfer Plasmid (Novagen) between the Pstl and Smal sites to prepare pBACSurfl-hMpl-FLAG 
Then, Sf9 cells were transformed with 4 jig of pBACSurfl-hMpl-FLAG using the Bac-N-Blue 
Transfection Kit (Invitrogen). The culture supernatant was collected after three-day incubation. 
Recombinant virus was isolated by plaque assays. The prepared virus stock was used to infect 
Sf9 cells, and the culture supernatant was collected. 
35 [0147] 

Soluble human Mpl protein was purified from the obtained culture supernatant as 



53 



JP 2004-071763 



described below. The culture supernatant was loaded onto a Q Sepharose Fast Flow 
(Amersham Biosciences) for adsorption, and the adsorbed protein was then eluted with 50 mM 
Na-phosphate buffer (pH7.2) containing 0.01% (v/v) Tween20 and 500 mM NaCl. After the 
eluates were loaded onto a FLAG M2 -Agarose (Sigma- Aldrich) for adsorption, the protein 
5 adsorbed was eluted with 100 mM glycine-HCl buffer (pH3.5) containing 0.01% (v/v) Tween20. 
Immediately after elution, the fraction obtained was neutralized with 1 M Tris-Cl (pH8.0) and 
the buffer was exchanged with PBS (-) and 0.01% (v/v) Tween20 using PD-10 columns 
(Amersham Biosciences). The purified soluble Mpl protein was referred to as "shMpl-FLAG". 
[0148] 

10 1 .4 Preparation of human Mpl-IgG Fc fusion protein 

Human fusion protein Mpl-IgG Fc gene was prepared according to the method by 
Bennett et al (Bennett, B. D. etal.J. Biol. Chem. (1991) 266: 23060-23067). Anucleotide 
sequence encoding the extracellular region of human Mpl (Gin 26 to Trp 491) was linked to a 
nucleotide sequence encoding the Fc region of human IgG-yl (a region downstream of Asp 216). 

15 ABstEll sequence (amino acids: Val-Thr) was attached to the junction as a fusion linker between 
these two regions. A 19-amino acid signal peptide derived form human IgG H chain variable 
region was used as the signal sequence. The resulting human fusion protein Mpl-IgG Fc gene 
was cloned into pCXND3 to construct pCXND3 -hMpl-Fc. 
[0149] 

20 The vector thus prepared (25 jag) was mixed with a PBS suspension of CHO-DG44 cells 

(1x10 cells/mL) in Gene Pulser cuvettes. The mixture was then pulsed at 1.5 kV and 25 \i¥D 
using Gene Pulser II (Bio-Rad). The CHO cells introduced with the DNA by electroporation 
were added to CHO-S-SFMII medium containing 500 ^ig/mL Geneticin and lx HT (Invitrogen). 
shMPL-Fc-expressing CHO cell line (CHO-hMpl-Fc) was then established through selection. 

25 [0150] 

Human Mpl-IgG Fc fusion protein was purified from the culture supernatant as 
described below. 

The culture supernatant was loaded onto a Q Sepharose Fast Flow (Amersham 
Biosciences) for adsorption, and then the adsorbed protein were eluted with 50 mM 

30 Na-phosphate buffer (pH7.6) containing 0.01% (v/v) Tween20 and 1 M NaCl. After the eluates 
were loaded onto a HiTrap protein G HP column (Amersham Biosciences) for adsorption, the 
adsorbed protein was eluted with 0. 1 M glycine-HCl buffer (pH2.7) containing 150 mM NaCl 
and 0.01% (v/v) Tween20. Immediately after elution, the obtained fraction was neutralized 
with 1 M Tris-Cl (pH8.0) and the buffer was exchanged with PBS (-) and 0.01% (v/v) Tween20 

35 using PD-10 columns (Amersham Biosciences). The purified soluble Mpl protein was referred 
to as "hMpl-Fc".

[0151] 

1.5 Immunization with shMpl-FLAG or BaF3 -human Mpl and hybridoma selection 

MRL/MpJUmmCrj-lpr/lpr mice (hereinafter abbreviated as "MRL/lpr mice"; purchased 
from Charles River, Japan) were immunized; the primary immunization was carried out at eight 
5 weeks of age. For every single mouse, an emulsion containing 1 00 |Lig of shMPL-FLAG 
combined with Freund's complete adjuvant (H37 Ra; Beckton Dickinson), was administered 
subcutaneously as the primary injection. As a booster injection, an emulsion containing 
shMPL-FLAG (50 ng per mouse) combined with Freund's incomplete adjuvant (Beckton 
Dickinson) was administered subcutaneously. . Three mice which have been immunized six 

10 times in total were subjected to a final injection of shMPL-FLAG (50 \ig per mouse) through the 
caudal vein. Cell fusion was achieved by mixing the mouse myeloma P3-X63Ag8Ul cells 
(P3U1; purchased from ATCC) and mouse splenocytes using polyethylene glycol 1500 (Roche 
Diagnostics). Hybridoma selection in HAT medium began the following day and culture 
supernatants were obtained. Screening was carried out by ELISA, using immunoplates 

1 5 immobilized with shMpl-FLAG or hMpl-Fc and the assayed cell growth activity of BaF3 -human 
Mpl as an index. In addition, Balb/C mice were immunized eleven times in total by 
administering BaF3-human Mpl (1 .0 x 10 cells per mouse) intraperitoneally over a period of 
one week to five months. Hybridomas were similarly prepared by cell fusion, and screened 
using the assayed cell growth activity of BaF3 -human Mpl as an index. Positive clones were 

20 isolated as single clones by limiting dilution and then cultured in a large scale. The culture 
supernatants were collected. 
[0152] 

1 .6 Analyses of anti-human Mpl antibodies 

Antibody concentrations were determined by carrying out a mouse IgG sandwich 
25 ELISA using goat anti-mouse IgG (gamma) (ZYMED) and alkaline phosphatase- goat 
anti-mouse IgG (gamma) (ZYMED), generating a calibration curve by GraphPad Prism 
(GraphPad Software; USA), and calculating the antibody concentrations from the calibration 
curve. Commercially available antibodies of the same isotype were used as standards. 
[0153] 

30 Antibody isotypes were determined by antigen-dependent ELISA using isotype-specific 

secondary antibodies. hMpl-Fc was diluted to 1 ng/mL with a coating buffer (0.1 mM NaHCC>3, 
pH9.6) containing 0.02% (w/v) NaN 3 , and then added to ELISA plates. The plates were 
incubated overnight at 4°C for coating. The plates were blocked with a diluent buffer (50 mM 
Tris-HCl (pH8.1) containing 1 mM MgCl 2 , 150 mM NaCl, 0.05% (v/v) Tween20, 0.02% (w/v) 

35 NaN3, 1% (w/v) BSA). After the addition of hybridoma culture supernatants, the plates were 
allowed to stand at room temperature for 1 hr. After washing with a rinse buffer (0.05% (v/v) 



55 



JP 2004-071763 



Tween20 in PBS), alkaline phosphatase-labeled isotype-specific secondary antibodies were 
added to the plates. Then, the plates were allowed to stand at room temperature for 1 hr. 
Color development was carried out using SIGMA 104 (Sigma- Aldrich) diluted to 1 mg/mL with 
a substrate buffer (50 mM NaHCC>3, pH9.8) containing 10 mM MgCk, and absorbance was 
5 measured at 405 nm using Benchmark Plus (Bio-Rad). 

[0154] 

The binding activities of an antibody to shMpl-FLAG and hMPL-Fc were determined 
by ELISA. ELIS A plates were coated with 1 (ag/mL of purified shMpl-FLAG or hMPL-Fc, and 
blocked with a diluent buffer. Hybridoma culture supernatants were added to the plates, and the 

10 plates were allowed to stand at room temperature for 1 hr. Then, alkaline phosphatase-labeled 
anti-mouse IgG antibodies (Zymed) were added to the plates. Color development was similarly 
carried out using the above method. Following a one-hour coloring reaction at room 
temperature, absorbance was measured at 405 nm and EC50 values were computed using 
GraphPad Prism. 

15 [0155] 

CHO-human Mpl cells and CHO-monkey Mpl cells were harvested, and suspended in 
FACS Buffer (1% FBS/ PBS) to a final concentration of 1 x 10 6 cells/mL. The suspensions 
were aliquoted into Multiscreen (Millipore) at 100 fil/well, and the culture supernatants were 
removed by centrifugation. Culture supernatants diluted to 5 jig/mL were added to the plates 

20 and incubated on ice for 30 min. The cells were washed once with FACS buffer, and incubated 
on ice for 30 min following the addition of an FITC-labeled anti-mouse IgG antibody (Beckman 
Coulter). After incubation, the mixture was centrifuged at 500 rpm for 1 min. The 
supernatants were removed, and then the cells were suspended in 400 jiL of FACS buffer. The 
samples were analyzed by flow cytometry using EPICS ELITE ESP (Beckman Coulter). An 

25 analysis gate was set on the forward and side scatters of a histogram to include viable cell 
populations. 

[0156] 

Agonistic activities of an antibody were evaluated using BaF3 -human Mpl and 
BaF3-monkey Mpl which proliferate in a TPO-dependent manner. Cells of each cell line were 

30 suspended at 4 x 10 5 cells/ml in RPMI 1640/10% FBS (Invitrogen), and each suspension was 
aliquoted into a 96-well plate at 60|al/well. A 40-jj.L aliquot of rhTPO (R&D) and hybridoma 
culture supernatants prepared at various concentrations was added into each well. The plates 
were then incubated at 37°C under 5% C0 2 for 24 hr. A 10-jaL aliquot of the Cell Count 
Reagent SF (Nacalai Tesque) was added into each well. After incubation for 2 hr, absorbance 

35 was measured at 450 nm (and at 655 nm as a control) using a Benchmark Plus. EC50 values 
were calculated using GraphPad Prism. 



56 JP 2004-071763 



The above analysis yielded a total of 163 clones of mouse monoclonal antibodies that 
bind to human Mpl. 

Among the anti-human Mpl antibodies to be described, TA136 was established from 
mice immunized with BaF-human Mpl and the others were established from mice immunized 
5 with shMpl-Flag. 

[0157] 

1.7 Purification of anti-human Mpl antibodies 

Anti-human Mpl antibodies were purified from hybridoma culture supernatants as 
described below. 

1 0 After the culture supernatants were loaded onto HiTrap protein G HP columns 

(Amersham Biosciences) for adsorption, the antibodies were eluted with 0.1 M glycine-HCl 
(pH2.7). Immediately after elution, the fractions were neutralized with 1 M Tris-Cl (pH9.0), 
dialyzed against PBS for one day, and the buffer was replaced. 
[0158] 

15 1.8 Determination of epitopes for the anti-human Mpl antibody VB22B 

Since the anti-human Mpl antibody VB22B can be used for Western blotting, a 
GST-fusion protein containing a partial sequence of human Mpl was constructed for VB22B 
epitope analysis. MG1 (Gln26 to Trp491) and MG2 (Gln26 to Leu274) regions were each 
amplified by PCR, and cloned into pGEX-4T-3 (Amersham Biosciences) to be expressed as GST 

20 fusion proteins. The resulting plasmid DNAs were transformed into DH5a to give 

transformants. A final concentration of 1 mM IPTG was added to the transformants in their 
logarithmic growth phase to induce the expression of GST fusion proteins. The bacterial cells 
were harvested after two hours of incubation. The cells were lysed by sonication. The lysates 
were centrifuged in XL-80 Ultracentrifuge (Beckman, Rotor 70.1Ti) at 35,000 rpm for 30 min. 

25 The culture supernatants were removed, and then the fusion proteins were purified using GST 
Purification Modules (Amersham Biosciences). The samples were separated by 
10%-SDS-PAGE, and then transferred onto a PVDF membrane. The membrane was Western 
blotted with the murine antibody VB22B. VB22B was found to recognize both MG-1 and 
MG-2, indicating that the VB22B epitope is located in the (Gln26 to Leu274) region. 

30 [0159] 

Then, GST fusion proteins containing the respective regions of human Mpl: MG3 
(Gln26 to Alal 89), MG4 (Gln26 to Prol06), MG5 (Gln26 to Glu259), and MG6 (Gln26 to 
Gly245) were prepared and analyzed by Western blotting using the same procedure described 
above. VB22B was found to recognize MG5 and MG6, but not MG3 and MG4. This 

35 suggests that the VB22B epitope is located within the (Alal 89 to Gly245) region. In addition, 
GST was fused with MG7 (Gln26 to Ala231) and MG8 (Gln26 to Pro217) to prepare GST fusion 



57 



JP 2004-071763 



proteins. VB22B recognized MG7 but not MG8, suggesting that the VB22B epitope is located 
in the (Gln2 1 7 to Ala23 1 ) region. Furthermore, GST fusion protein containing MG 1 0 (Gln2 1 3 
to Ala231) was recognized by VB22B, suggesting that the VB22B epitope is located within the 
limited region of 19 amino acids between Gln213 and Ala231. 
5 [0160] 

1 .9 Kinetic analyses of the antigen-antibody reaction for anti-human Mpl antibody VB22B 

Since the anti-human Mpl antibody VB22B binds to soluble recombinant Mpl, kinetic 
analyses of the antigen-antibody reaction between VB22B IgG and human Mpl-IgG Fc fusion 
protein were carried out as described in Example 1 .4. The Sensor Chip CMS (Biacore) was 

10 placed in Biacore 2000 (Biacore), and human Mpl-IgG Fc fusion protein was immobilized onto 
the chip by amine-coupling methods. Then, 1.25 to 20 |j,g/mL of VB22B IgG solution was 
prepared using HBS-EP Buffer (Biacore), and injected over the chip surface for 2 min to reveal 
the binding region. Then, HBS-EP Buffer was injected over the chip surface for 2 min to reveal 
the dissociation region. VB22B IgG bound to the human Mpl-IgG Fc fusion protein on the 

15 sensor chip was removed by injecting 10 mM NaOH over the sensor chip for 15 sec, and the chip 
was recovered. HBS-EP Buffer was used as the running buffer, and the flow rate was 20 
|iL/min. Using the BIAevaluation Version 3.1 (Biacore) software, the reaction rate constant at 
each concentration was calculated from the sensorgrams. The dissociation constant (KD) for 
VB22B IgG was determined to be 1.67 ± 0.713 x 10" 9 M. 

20 [0161] 

[Example 2] Preparation of single-chain anti-human Mpl antibodies 

Among the prepared anti-human Mpl antibodies, 23 types of antibodies, which exhibit 
higher binding activities and agonistic activities, were selected to construct expression systems 
for single-chain antibodies using genetic engineering techniques. An exemplary method for 

25 constructing a single-chain antibody derived from the anti-human Mpl antibody VB22B is 
described below. 
[0162] 

2.1 Cloning of the anti-human Mpl antibody variable region 

The variable region was amplified by RT-PCR using total RNA extracted from 
30 hybridomas producing anti-human Mpl antibodies. Total RNA was extracted from 1x10 
hybridoma cells using the RNeasy Plant Mini Kit (QIAGEN). 
[0163] 

A 5 5 -terminal fragment of the gene was amplified from 1 jag of total RNA by the 
SMART RACE cDNA Amplification Kit (Clontech), using a synthetic oligonucleotide 
35 MHC-IgG2b (SEQ ID NO: 166) complementary to mouse IgG2b constant region or a synthetic 
oligonucleotide kappa (SEQ ID NO: 167) complementary to mouse k chain constant region.

[0166] 

The PCR products were purified from agarose gel using the QIAquick Gel Extraction 
Kit (QIAGEN), and cloned into a pGEM-T Easy Vector (Promega). The nucleotide sequence 
was then determined using the ABI 3700 DNA Analyzer (Perkin Elmer).

The nucleotide sequence of cloned VB22B H chain variable region (hereinafter 
abbreviated as "VB22B-VH") is shown in SEQ ID NO: 117, and its amino acid sequence is 
shown in SEQ ID NO: 118. The nucleotide sequence of the L chain variable region (hereinafter 
abbreviated as "VB22B-VL") is shown in SEQ ID NO: 119, and its amino acid sequence is

[0168] 

2.2 Preparation of expression vectors for anti-human Mpl diabodies 

The gene encoding VB22B single-chain Fv (hereinafter abbreviated as "VB22B 
diabody") containing a five-amino acid linker sequence was constructed, by linking a nucleotide 
25 sequence encoding a (Gly4Ser)i linker to the VB22B-VH-encoding gene at its 3' end and to the 
VB22B-VL-encoding gene at its 5 ' end; both of which have been amplified by PCR. 
[0169] 

The VB22B-VH forward primer, 70115HF, (SEQ ID NO: 168) was designed to contain 
an EcoRI site. The VB22B-VH reverse primer, 33415HR, (SEQ ID NO: 169) was designed to 
30 hybridize to a DNA encoding the C terminus of VB22B-VH, and to have a nucleotide sequence 



59 JP 2004-071763 



encoding the (Gly4Ser)i linker and a nucleotide sequence hybridizing to the DNA encoding the 
N terminus of VB22B-VL. The VB22B-VL forward primer, 33-11 5LF, (SEQ ID NO: 1 70) was 
designed to have a nucleotide sequence encoding the N terminus of VB22B-VL, a nucleotide 
sequence encoding the (Gly4Ser)i linker, and a nucleotide sequence encoding the C terminus of 
5 VB22B-VH. The VB22B-VL reverse primer, 33-115LR, (SEQ ID NO: 171) was designed to 
hybridize to a DNA encoding the C terminus of VB22B-VL and to have a nucleotide sequence 
encoding a FLAG tag (Asp Tyr Lys Asp Asp Asp Asp Lys/SEQ ID NO: 172) and a Notl site. 
[0170] 

In the first round of PCR, two PCR products: one containing VB22B-VH and a linker 
1 0 sequence, and the other containing VB22B- VL and the identical linker sequence, were 
synthesized by the procedure described below.

(QIAGEN), and then cloned into pCXND3 to prepare pCXND3-VB22B db. 
[0175] 

2.3 Preparation of expression vectors for anti-human Mpl antibody sc(Fv)2 

To prepare expression plasmids for the modified antibody [sc(Fv)2] comprising two 
1 5 units of H chain variable region and two units of L chain variable region derived from VB22B, 
the above-described pCXND3-VB22B db was modified by PCR using the procedure shown 
below. The process for constructing the sc(Fv) 2 gene is illustrated in Fig. 1 . 
[0176] 

First, PCR method was carried out to amplify (a) the VB22B-VH-encoding gene in 
20 which a nucleotide sequence encoding a 15-amino acid linker (Gly4Ser)3 was added to its 3' end; 
and (b) the VB22B-VL-encoding gene containing the identical linker nucleotide sequence added 
to its 5' end. The desired construct was prepared by linking these amplified genes. Three new 
primers were designed in this construction process. The VB22B-VH forward primer, 
VB22B-fpvu, (primer A; SEQ ID NO: 173) was designed to have an EcoKL site at its 5 5 end and 
25 to convert Gln22 and Leu23 of VB22B db into a Pvull site. The VB22B-VH reverse primer, 
sc-rL15, (primer B; SEQ ID NO: 174) was designed to hybridize to a DNA encoding the C 
terminus of VB22B-VH, and to have a nucleotide sequence encoding the (Gly4Ser) 3 linker, as 
well as a nucleotide sequence hybridizing to a DNA encoding the N terminus of VB22B-VL. 
The VB22B-VL forward primer, sc-fL15, (primer C; SEQ ID NO: 175) was designed to have a 
30 nucleotide sequence encoding the N terminus of VB22B-VL, a nucleotide sequence encoding the 
(Gly4Ser)3 linker, and a nucleotide sequence encoding the C terminus of VB22B-VH. 
[0177] 

In the first-round PCR, two PCR products: one comprising VB22B-VH and a linker 
sequence, and the other comprising VB22B-VL and the identical linker sequence, were 
35 synthesized by the procedure described below. 

The composition of the PCR reaction solution (50 \xL in total) is shown below.

JP 2004-071763 



A fragment to be inserted into the Pvull site of pBacPAK9-scVB22B was prepared. 
Specifically, the fragment has a Pvull recognition site at both ends and a nucleotide sequence, in 
which a gene encoding the VB22B-VH N-terminus is linked, via a (Gly4Ser)3 linker-encoding 
nucleotide sequence, to a gene encoding the amino acid sequence of an N-terminus-deleted 
5 VB22B-VH linked to VB22B-VL via the (Gly4Ser) 3 linker. Two primers were newly designed 
to prepare the fragment by PCR. The forward primer for the fragment of interest, Fv2-f (primer 
E; SEQ ID NO: 176), was designed to have a PvwII site at its 5' end and a VB22B-VH 5 5 -end 
sequence. The reverse primer for the fragment of interest, Fv2-r (primer F; SEQ ID NO: 177), 
was designed to hybridize to a DNA encoding the C terminus of VB22B-VL, and to have a Pvull 
10 site, a nucleotide sequence encoding the (Gly4Ser)3 linker, and a nucleotide sequence hybridizing 
to a DNA encoding the N terminus of VB22B-VH. PCR was carried out using 
pBacPAK9-scVB22B as a template as described below.

The PCR products of about 800 bp were purified from agarose gel using the QIAquick 
Gel Extraction Kit (QIAGEN), and then cloned into the pGEM-T Easy Vector (Promega). 
25 After sequencing, the plasmid was digested with Pvull (TaKaRa), and the fragment of interest 
was recovered. The recovered fragment was ligated to pBacPAK9-scVB22B pre-digested with 
PvwII (TaKaRa) to construct pBacPAK9-VB22B sc(Fv) 2 . After the resulting vector was 
digested with EcoRI and Notl (both from TaKaRa), the fragment of about 1,600 bp was purified 
from agarose gel using the QIAquick Gel Extraction Kit (QIAGEN). The fragment was then 
30 cloned into a pCXND3 expression vector to construct pCXND3-VB22B sc(Fv)2.

2.4 Expression of single-chain anti-human Mpl antibody in animal cells 

A cell line stably expressing the single-chain antibody was prepared from CHO-DG44 
cells as described below. Gene transfer was achieved by electroporation using a Gene Pulser II 
(Bio-Rad). An expression vector (25 fig) and 0.75 mL of CHO-DG44 cells suspended in PBS 
5 (1 x 10 7 cells/mL) were mixed. The resulting mixture was cooled on ice for 10 min, transferred 
into a cuvette, and pulsed at 1.5-kV and 25 p,FD. After a ten-minute restoration period at room 
temperature, the electroporated cells were plated in CHO-S-SFMII medium (Invitrogen) 
containing 500 jig/mL Geneticin (Invitrogen). CHO cell lines expressing the single-chain 
antibody were established through selection. A cell line stably expressing VB22B sc(Fv)2 and 
1 0 its culture supernatants were obtained by this method. 

[0187] 

The transient expression of the single-chain antibody was achieved using COS7 cells as 
described below. An expression vector (10 jig) and 0.75 mL of COS7 cells suspended in PBS 
(1x10' cells/mL) were mixed. The resulting mixture was cooled on ice for 10 min, transferred 

1 5 into a cuvette, and then pulsed at 1 .5-kV and 25 \xFD. After a ten-minute restoration period at 
room temperature, the electroporated cells were plated in DMEM/10% FBS medium (Invitrogen). 
The cells were incubated overnight and then washed with PBS. CHO-S-SFMII medium was 
added and the cells were cultured for about three days. The culture supernatants for preparing 
the VB22B diabody were thus prepared. 

20 [0188] 

2.5 Quantitation of single-chain anti-human Mpl antibodies in culture supernatants 

The culture supernatant concentration of the single-chain anti-human Mpl antibody 
transiently expressed in COS cells was determined using surface plasmon resonance. A sensor 
chip CM5 (Biacore) was placed in Biacore 2000 (Biacore). ANTI-FLAG® M2 Monoclonal 

25 Antibody (Sigma- Aldrich) was immobilized onto the chip. An appropriate concentration of 
sample was injected over the chip surface at a flow rate of 5 mL/sec, and 50 mM diethylamine 
was used to dissociate the bound antibody. Changes in the mass during sample injection were 
recorded, and the sample concentration was calculated from the calibration curve prepared using 
the mass changes of a standard sample. dbl2E10 (see WO 02/33073 and WO 02/33072) was 

30 used as the diabody standard, and 12E10 sc(Fv)2 which has the same gene structure as that of 
sc(Fv) 2 was used as the sc(Fv)2 standard. 
[0189] 

2.6 Purification of anti-human Mpl diabodies and single-chain antibodies 

The culture supernatants of VB22B diabody-expressing COS7 cells or CHO cells was 
35 loaded onto an Anti-Flag M2 Affinity Gel (Sigma- Aldrich) column equilibrated with a 50 mM 
Tris-HCl buffer (pH7.4) containing 150 mM NaCl and 0.05% Tween20. The absorbed 



64 JP 2004-071763 



antibodies were eluted with 100 mM glycine-HCl (pH3.5). The fractions eluted were 
immediately neutralized with 1 M Tris-HCl (pH8.0), and loaded onto a HiLoad 26/60 Superdex 
200 pg (Amersham Biosciences) column for gel filtration chromatography. PBS/0.01% 
Tween20 was used in the gel filtration chromatography. 
5 [0190] 

VB22B sc(Fv) 2 was purified from the culture supernatants of VB22B sc(Fv)2-expressing 
COS7 cells or CHO cells under the same conditions used for purifying the diabodies. A 
large-scale preparation of VB22B sc(Fv)2 was prepared by loading the CHO cell culture 
supernatants onto a Macro-Prep Ceramic Hydroxyapatite Type I (Bio-Rad) column equilibrated 

10 with a 20 mM phosphate buffer (pH6.8), and eluting the VB22B sc(Fv) 2 in a stepwise manner 
with 250 mM phosphate buffer (pH6.8). The eluted fraction was concentrated on an ultrafilter, 
and then fractionated by gel filtration chromatography using a HiLoad 26/60 Superdex 200 pg 
(Amersham Biosciences) column, and a fraction corresponding to the molecular weight range of 
about 40 kD to 70 kD was obtained. The fraction was loaded onto an Anti-Flag M2 Affinity 

15 Gel column equilibrated with a 50 mM Tris-HCl buffer (pH7.4) containing 150 mM NaCl and 
0.05% Tween20. The absorbed antibody was eluted with 100 mM glycine-HCl (pH3.5). The 
eluted fraction was immediately neutralized with 1 M Tris-HCl (pH8.0), and loaded onto a 
HiLoad 26/60 Superdex 200 pg (Amersham Biosciences) column for gel filtration 
chromatography. 20 mM acetate buffer (pH6.0) containing 150 mM NaCl and 0.01% Tween80 

20 was used in the gel filtration chromatography. In each purification step, the presence of the 

diabody and sc(Fv)2 in the samples was confirmed by SDS-PAGE and Western blotting using an 
anti-Flag antibody (Sigma-Aldrich). 
[0191] 

2.7 Binding activity analyses of single-chain anti-human Mpl antibodies by flow cytometry 
25 CHO-human Mpl, CHO-monkey Mpl, and CHO-mouse Mpl cells were recovered and 

suspended in FACS buffer (1% FBS/PBS) to a final concentration of 1 x 10 6 cells/mL. Cell 
suspensions were aliquoted at 100-jaL/well into the Multiscreen-HV Filter Plates (Millipore). 
After centrifugation, the supernatant was removed. An appropriate concentration of diabody or 
sc(Fv)2 was added into each well and incubated on ice for 30 min. The cells were washed once 
30 with 200 |iL of FACS buffer, and incubated on ice for 30 min following the addition of 10 jag/mL 
ANTI-FLAG® M2 Monoclonal Antibody (Sigma-Aldrich). The cells were then washed once 
with 200 jj.L of FACS buffer, and a lOOx-diluted FITC-labeled anti-mouse IgG antibody 
(Beckman Coulter) was added to the plate. The plate was incubated on ice for 30 min. After 
centrifugation, the supernatant was removed. The cells were suspended in 400 jiL of FACS 
35 Buffer, and then analyzed by flow cytometry using EPICS ELITE ESP (Beckman Coulter). An 
analysis gate was set on the forward and side scatters of a histogram to include viable cell 



65 JP 2004-071763 



populations. 

[0192] 

The binding activity of the purified VB22B sc(Fv) 2 to various Mpl molecules expressed 
in CHO cells was determined (Fig. 2). VB22B sc(Fv) 2 was found to specifically bind to 
5 CHO-human Mpl and CHO-monkey Mpl but not to the host cell CHO or CHO-mouse Mpl. 
This binding characteristic of VB22B sc(Fv)2 is comparable to those of VB22B IgG, indicating 
that the antibody binding site remains unaltered by reduction of molecular weight. 

[0193] 

2.8 Analyses of TPO-like agonistic activity for single-chain anti-human Mpl antibodies 
10 TPO-like agonistic activity was assessed using BaF3 -human Mpls or BaF3 -monkey 

Mpls that proliferate in a TPO-dependent manner. 

Cells from each cell line were washed twice with RPMI 1640/1% FBS (fetal bovine 
serum) (Invitrogen), and then suspended in RPMI 1640/10% FBS to a concentration of 4 x 10 5 
cells/mL. Cell suspensions were aliquoted at 60-jj.L/well into a 96-well plate. Various 
1 5 concentrations of rhTPO (R&D) and COS7 culture supernatants or purified samples were 
prepared, and a 40-(j,L aliquot was added into each well. The plates were then incubated at 
37°C under 5% C0 2 for 24 hr. Immediately after a 10-p.L aliquot of WST-8 reagent (Cell 
Count Reagent SF; Nacalai Tesque) was added into each well, absorbance was measured at 450 
nm (and at 655 nm as a control) using Benchmark Plus. After two hours of incubation, 
20 absorbance was again measured at 450 nm (and at 655 nm as a control). The WST-8 reagent 
changes colors at 450 nm in a color reaction that reflects the viable cell count. The TPO-like 
agonistic activity was assessed using the change in absorbance during the two-hour incubation as 
an index. EC50 values were computed using GraphPad Prism. 
[0194] 

25 TPO-like agonistic activity was assayed using the human leukemia cell line M-07e 

(purchased from DSMZ) which proliferates TPO-dependently. M-07e cells were washed twice 
with RPMI 1640/1% FBS, and then suspended in RPMI 1640/10% FBS to a concentration of 5 x 
10 5 cells/mL. The resulting cell suspension was aliquoted at 50-p.L/well into a 96-well plate. 
Various concentrations of rhTPO and COS7 culture supernatants or purified samples were 

30 prepared, and a 50-jj.L aliquot was added into each well. The plates were then incubated at 
37°C under 5% C0 2 for 48 hr. Immediately after a 10-^L aliquot of WST-8 reagent (Cell 
Count Reagent SF; Nacalai Tesque) was added to each well, absorbance of was measured at 450 
nm (and at 655 nm as a control) using a Benchmark Plus. After four hours of incubation, 
absorbance was again measured at 450 nm (and at 655 nm as a control). The TPO-like 

35 agonistic activity was assayed using the change in absorbance during the four-hour incubation as 
an index. 



66 JP 2004-071763 



[0195] 

Purified VB22B IgG, VB22B diabody, and VB22B sc(Fv) 2 were assayed for their 
TPO-like agonistic activities using BaF3 -human Mpl, BaF3 -monkey Mpl 5 and M-07e. The 
results are shown in Figures 3, 4, and 5, respectively. The presence of bivalent antigen-binding 
5 domains in a single antibody molecule is essential for its agonistic activity. The distance and 
angle between two antigen-binding domains can also be important factors (see WO 02/33073 
and WO 02/33072). Similar results were obtained for the newly isolated anti-human Mpl 
antibodies. Specifically, the agonistic activities of VB22B diabody and VB22B sc(Fv) 2 (EC50 = 
61 pM and 27 pM in BaF-human Mpl, respectively) were higher than that of VB22B IgG (EC50 

10 > 30 nM in BaF-human Mpl), and were equivalent to or higher than that of the 

naturally-occurring human TPO ligand (EC50 = 76 pM in BaF-human Mpl). The VB22B 
diabody activity was lower than that of VB22B sc(Fv)2. This suggests that the structure of a 
single-chain antibody is greatly altered by its molecular shape and the length of the linker 
sequence, which in turn changes the agonistic activity. Sixteen types of the single-chain 

1 5 anti-human Mpl antibodies were obtained, each exhibiting a high agonistic activity. The amino 
acid sequences of the H chain and L chain variable regions of the representative antibodies are 
shown in Figures 6 and 7, respectively. 
[0196] 

2.9 Humanization of single-chain anti-human Mpl antibody 

20 Antibody sequence data for the humanization of VB22B sc(Fv)2 were obtained from the 

Kabat Database (ftp://ftp.ebi.ac.uk/pub/databases/kabat/), and homology searches were carried 
out independently for the H chain variable region and the L chain variable region. As a result, 
the H chain variable region was found to be highly homologous to DN13 (Smithson S. L. et al. 9 
Mol Immunol. (1999) 36: 113-124). The L chain variable region was found to be highly 

25 homologous to ToP027 (Hougs L. et ai, J. Immunol. (1999) 162: 224-237). Humanized 
antibodies were prepared by inserting a complementarity-determining region (hereinafter 
abbreviated as "CDR") into the framework regions (hereinafter abbreviated as "FR") of the 
above antibodies. The humanized antibody sc(Fv) 2 was expressed in CHO-DG44 cells, and its 
agonistic activity was assessed using BaF-human Mpl. The agonistic activity was used as an 

30 index to generate a humanized VB22B sc(Fv)2 which has agonistic activity equivalent to that of 
murine VB22B sc(Fv)2 by replacing one or more amino acids in its framework region. 
[0197] 

Specifically, synthetic oligo-DNAs of approximately 50 nucleotides in length were 
designed as to make 20 of these nucleotides available for hybridization, and the synthetic 
35 oligo-DNAs were assembled by PCR to prepare genes that encode the respective variable 

regions. Using the resulting genes, sc(Fv)2 was similarly prepared by the method described in 



JP 2004-071763 



Example 2.3. The respective DNAs were cloned into a pCXND3 expression vector to construct 
three kinds of expression vectors, pCXND3-hVB22B p-z sc(Fv) 2 , pCXND3-hVB22B g-e sc(Fv) 2 , 
and pCXND3-hVB22B e sc(Fv) 2 , to which the humanized VB22B sc(Fv) 2 is inserted. The 
nucleotide sequence and the amino acid sequence of hVB22B p-z sc(Fv) 2 in the plasmid are 
5 shown in SEQ ID NOs: 1 and 2. The nucleotide sequence and the amino acid sequence of 

hVB22B g-e sc(Fv) 2 are shown in SEQ ID NOs: 253 and 254. The nucleotide sequence and the 
amino acid sequence of hVB22B e sc(Fv) 2 are shown in SEQ ID NOs: 259 and 260. The 
nucleotide sequence and the amino acid sequence of murine VB22B sc(Fv) 2 are shown in SEQ 
ID NOs: 263 and 264. The plasmids were expressed in CHO-DG44 cells by the method 

10 described in Example 2.4 and the purification was done using the method described in Example 
2.6. The TPO-like agonistic activities of the purified samples were similarly determined using 
the method described in Example 2.8. The TPO-like agonistic activities of the purified murine 
VB22B sc(Fv) 2 , and humanized hVB22B e sc(Fv) 2 and hVB22B g-e sc(Fv) 2 in BaF3 -human 
Mpl were assessed. The results are shown in Figures 19. The humanized VB22B sc(Fv) 2 

1 5 showed comparable agonistic activities, suggesting that the humanization has no influence on the 
activity. 

[0198] 

[Example 3] Preparation of anti-Mpl diabodies by the AGS method 

Anti-Mpl diabodies having agonistic activity were prepared by an Autocrine Growth 
20 Selection (AGS) method (see, WO 03/91424). 

[0199] 

3 . 1 Construction of a retrovirus library 

Spleens were isolated from MRL/lpr mice immunized with shMPL-Flag by the method 
described in Example 1.5, and homogenized in TRIZOL Reagent (Invitrogen) using a Dounce 

25 homogenizer. After chloroform addition, the homogenized sample was shaken vigorously, the 
aqueous phase was removed and total RNA was extracted by isopropanol precipitation. mRNA 
was purified using a PolyATract System 1000 (Promega). Reverse transcription of 2.5 |ug 
mRNA was carried out at 42°C for 50 min using the Superscript First strand synthesis system for

3.2 Establishment of autonomously replicating cell lines by the AGS method 

The resulting library was transfected into a packaging cell, Pt-E 5 (Morita, S. et al 9 Gene 
therapy 7: 1063-1066) using FuGENE 6 (Roche Diagnostics). Specifically, Pt-E was plated 
5 onto 6-cm dishes and cultured in DMEM/10% FBS (Invitrogen). A mixture of FuGENE 6 and 
the library was added to the plate the following day. The culture medium was exchanged the 
next day, and the culture supernatant was collected 24 hours after that. 10 jag/mL polybrene 
(Hexadimethrine Bromide; Sigma) and 2 ng/mL mIL-3 were added to the culture supernatant 
containing recombinant virus particles. The viral solution was used to infect the BaF-monkey 

10 Mpl target cells. The cells were washed with PBS the following day, and suspended in RPMI 
1640/10% FBS without mIL-3. The suspension was plated onto a 96-well plate at a cell density 
of 1,000 cells/well. Autonomously replicating cell lines (AB317 and AB324) were obtained 
after seven days of incubation. Genomic DNAs were extracted from these cells using a 
DNeasy Tissue Kit (QIAGEN), and the antibody genes were amplified by PCR.

30 3.3 Activity assays of the diabodies obtained by AGS method 



72 



JP 2004-071763 



Each of the anti-Mpl diabodies obtained above was inserted into the pCXND3 
expression vector. The PCR primers used are a synthetic oligonucleotide complementary to the 
5 5 end of the diabody and containing an EcoRI site, and a synthetic oligonucleotide 
complementary to the nucleotide sequence of the 3 5 end of the diabody and containing a FLAG 
5 tag and a Noil site. The PCR product thus obtained was inserted into pCXND3 between the 
EcoRI and Notl sites. The diabody was expressed transiently in COS7 cells by the method 
described in Example 2.4. The culture supernatant was removed and the activity of the diabody 
was evaluated. 

[0213] 

10 The binding activities of the diabodies were assessed by flow cytometry using CHO 

cells that express Mpl derived from various species (Fig. 8). AB3 17 was proven to bind to 
CHOmouse Mpl. 
[0214] 

The TPO-like agonistic activities of the diabodies were evaluated using BaF-human Mpl, 
15 BaF-monkey Mpl, and BaF-mouse Mpl (Figures 9, 10, and 11). AB317 had the highest 

agonistic activity against human, monkey, and mouse Mpl, whereas AB324 showed the highest 
agonistic activity against human and monkey Mpl. 
[0215] 

This proves that anti-Mpl diabodies having high agonistic activity can be obtained by 
20 the AGS method. 

[0216] 

[Example 4] Agonistic activity assays of the anti-Mpl antibodies against mutant Mpl in 
congenital amegakaryocytic thrombocytopenia (CAMT) patients 

4.1 Establishment of BaF3 cell lines introduced with the mutant Mpl observed in CAMT patients 
25 Mutations on G305C (R102P), C769T (R257C), and C823A (P275T) have been 

reported in the Mpl gene of CAMT patients. The respective expression vectors carrying the 
Mpl gene mutations were constructed and introduced into BaF3 cells. The following Mpl gene 
fragments were constructed: normal Mpl gene (nucleotide sequence, SEQ ID NO: 246; amino 
acid sequence, SEQ ID NO: 123); gene G305C in which C is substituted for 305th nucleotide G 
30 relative to the initiation codon (nucleotide sequence, SEQ ID NO: 247; amino acid sequence, 
SEQ ID NO: 248); gene C769T in which T is substituted for 769th nucleotide C (nucleotide 
sequence, SEQ ID NO: 249; amino acid sequence, SEQ ID NO: 250); and gene C823A in which 
A is substituted for 823rd nucleotide C (nucleotide sequence, SEQ ID NO: 251; amino acid 
sequence, SEQ ID NO: 252). These DNA fragments were digested with EcoRI and Sail, and 
35 inserted between the EcoRI and Sail sites on the animal cell expression vector pCOS2-Ha to 
prepare pCOS2-hMPLfullG305C, P COS2-hMPLfullC769T, and pCOS2-hMPLfullC823 A. 



73 



JP 2004-071763 



[0217] 

The genes were introduced into BaF3 cells by the procedure described in Example 1.1.1 
to establish BaF3 cell lines expressing each Mpl gene: BaF3-human MPL (G305C), 
BaF3-human MPL (C769T), and BaF3-human MPL (C823A). After the selection, the cells 
5 were cultured and passaged using RPMI 1640 containing 1 ng/mL mIL-3 and 10% FBS. 

[0218] 

4.2 Preparation of anti-human Mpl diabody and sc(Fv)2 

Among the amino acid sequences shown in Figures 6 and 7, expression vectors were 
prepared for the diabodies VB8B, VB45B, VB33, VB140, VB157, and TA136 using the same 

10 procedure described in Example 2.2.2. The prepared expression vectors were introduced into 
COS7 cells by the same procedure described in Example 2.2.4. The supernatant concentration 
of each diabody was determined by the method of Example 2.2.5. The sc(Fv)2 expression 
vector for TA136 was prepared by the same procedure described in Example 2.2.3. The vector 
was introduced into CHO-DG44 cells by the same procedure described in Example 2.2.4. 

1 5 sc(Fv)2 was purified from the culture supernatant thus obtained using the same method described 
in Example 2.2.6. 
[0219] 

4.3 Agonistic activity assays of sc(Fv)2 and the anti-human Mpl diabodies 

The prepared diabodies and sc(Fv)2 were assayed for their agonistic activities in normal 
20 Mpl and mutant Mpl in BaF3 cells by the same procedure described in Example 2.2.8. The 
agonistic activities in BaF3 -human Mpl and BaF3-human Mpl (G305C) were compared using 
the culture supernatants of cells expressing the diabodies. The TA136 diabody (TA136 db) was 
shown to have a low agonistic activity in BaF3 -human Mpl cells expressing the normal Mpl gene, 
and a high agonistic activity in BaF3 -human Mpl (G305C) cells expressing the mutant Mpl gene. 
25 hTPO and the rest of the diabodies did not show a high agonistic activity in BaF3 -human Mpl 
(G305C) cells (Figures 12 and 13). 
[0220] 

In addition, the agonistic activities of the TA136 diabody and TA136 sc(Fv)2 in 
BaF3 -human Mpl, BaF3 -human Mpl (G305C), BaF3 -human Mpl (C769T), and BaF3 -human 

30 Mpl (C823A) cells were assessed using a purified sample of the diabody. Compared with 
hTPO and the TA136 diabody, TA136 sc(Fv)2 exhibited a higher agonistic activity in all three 
types of the TPO receptor mutant cell lines (Figures 15, 16 and 17). Furthermore, it was shown 
that in BaF3 -human Mpl cells expressing the normal Mpl gene, the TA136 diabody exhibited a 
lower activity than hTPO. However, an agonistic activity equivalent to that of hTPO was 

35 achieved by converting the diabody into sc(Fv)2 (Fig. 14).

[Document Name] Abstract 
[Abstract] 

[Problems to be Solved] An objective of the present invention is to provide novel anti-Mpl 
5 antibodies having TPO-agonistic activity. 

[Means for Solving the Problems] Anti-human Mpl antibodies were isolated and purified, and 
then anti-human Mpl diabodies and anti-human Mpl sv(Fv) 2 were purified using genetic 
engineering techniques. Furthermore, the present inventors succeeded in humanizing 
anti-human Mpl sc(Fv)2. 

10 The diabodies and sc(Fv)2 were assayed for TPO-like agonistic activity, and were found 

to have activities higher than those of anti-human Mpl antibodies, or activities equivalent to or 
higher than those of naturally-occurring human TPO ligand.
